The group now known as Chicago began on February 15, 1967, at a meeting involving saxophonist Walter Parazaider, guitarist Terry Kath, drummer Danny Seraphine, trombonist James Pankow, trumpet player Lee Loughnane, and keyboardist/singer Robert Lamm. Kath, Parazaider, and Seraphine had played together previously in two other groups—Jimmy Ford and the Executives, and the Missing Links.: 29–49 Parazaider had met Pankow and Loughnane when they were all students at DePaul University.: 48–49 Lamm, a student at Roosevelt University, was recruited from his group, Bobby Charles and the Wanderers.: 49 The group of six called themselves the Big Thing, and like most other groups playing in Chicago nightclubs, played Top 40 hits. Realizing the need for both a tenor to complement baritones Lamm and Kath, and a bass player because Lamm's use of organ bass pedals did not provide "adequate bass sound", local tenor and bassist Peter Cetera was invited to join the Big Thing in late 1967.: 58–59
While gaining some success as a cover band, the group began working on original songs. In June 1968, at manager James William Guercio's request, the Big Thing moved to Los Angeles, California, where they signed with Columbia Records and changed their name to Chicago Transit Authority. While performing on a regular basis at the Whisky a Go Go nightclub in West Hollywood, the band got exposure to more famous musical artists of the time, subsequently opening for Janis Joplin and Jimi Hendrix.: 77–78, 106–107 Group biographer William James Ruhlmann recorded Walt Parazaider as saying that Jimi Hendrix once told him: "'Jeez, your horn players are like one set of lungs and your guitar player is better than me.'"
In 1970, less than a year after its first album, the band released a second album, titled Chicago (retroactively known as Chicago II), which is another double-LP. The album's centerpiece track is a seven-part, 13-minute suite composed by Pankow called "Ballet for a Girl in Buchannon". The suite yielded two top ten hits: "Make Me Smile" (No. 9 U.S.) and "Colour My World", both sung by Kath. Among the other tracks on the album: Lamm's dynamic but cryptic "25 or 6 to 4" (Chicago's first Top 5 hit), which is a reference to a songwriter trying to write at 25 or 26 minutes before 4 o'clock in the morning,: 109 and was sung by Cetera with Terry Kath on guitar; the lengthy war-protest song "It Better End Soon"; and, at the end, Cetera's 1969 Moon landing-inspired "Where Do We Go from Here?" The double-LP album's inner cover includes the playlist, the entire lyrics to "It Better End Soon", and two declarations: "This endeavor should be experienced sequentially", and, "With this album, we dedicate ourselves, our futures and our energies to the people of the revolution. And the revolution in all of its forms." The album was a commercial success, rising to number four on the Billboard 200, and was certified gold by the Recording Industry Association of America (RIAA) in 1970, and platinum in 1991. The band was nominated for two Grammy Awards as a result of this album, Album of the Year and Best Contemporary Vocal Performance by a Duo, Group or Chorus.
The band released LPs at a rate of at least one album per year from their third album in 1971 on through the 1970s. During this period, the group's album titles primarily consisted of the band's name followed by a Roman numeral, indicating the album's sequence in their canon. The exceptions to this scheme were the band's fourth album, a live boxed set entitled Chicago at Carnegie Hall, their twelfth album Hot Streets, and the Arabic-numbered Chicago 13. While the live album itself did not bear a number, the four discs within the set were numbered Volumes I through IV.
Besides recording and touring, during the busy 1970s, Chicago also made time for a movie appearance and several television appearances of note. In 1972, Guercio produced and directed Electra Glide in Blue, a film about an Arizona motorcycle policeman. Released in 1973, the film stars Robert Blake and features Cetera, Kath, Loughnane, and Parazaider in supporting roles. The group also appears prominently on the film's soundtrack. Chicago made its "television variety debut" in February 1973 when they were the only rock musicians invited to appear on a television special honoring Duke Ellington, Duke Ellington... We Love You Madly, which aired on CBS. They performed the Ellington composition, "Jump for Joy". In July 1973, the group starred in a half-hour television special produced by Dick Clark, Chicago in the Rockies, which aired in prime time on ABC. The show was filmed on location at Caribou Ranch, the 3,000-acre ranch-turned-recording studio located outside of Boulder, Colorado, owned by Chicago's producer, James William Guercio. The only musical guest on the show was Al Green, who was rated the number-one male vocalist of 1972, and whom Rolling Stone magazine named "Rock and Roll Star of the Year". That special was followed by a second hour-long special the next year, Chicago ... Meanwhile, Back at the Ranch, which aired in prime time on ABC in August 1974. Chicago ... Meanwhile, Back at the Ranch was again shot on location at Caribou Ranch and was again produced by Dick Clark. Singer Anne Murray and country music star Charlie Rich were guests on the show. Clark produced a third television special starring Chicago, Chicago's New Year's Rockin' Eve 1975, which aired on ABC on December 31, 1974. Musical guests on the 1+1⁄2-hour-long show included the Beach Boys, the Doobie Brothers, Olivia Newton-John, and Herbie Hancock. It was the third Rockin' Eve Clark had produced, and it competed with Guy Lombardo's traditional New Year's Eve television show which aired on a different network and was in its 45th consecutive year of broadcast. Clark hoped the Rockin' Eve format would become an "annual TV custom".
The year 1978 began with a split with Guercio. Chicago had recorded its last five studio albums Chicago VI, VII, VIII, X, and XI, and had made two television specials at Guercio's Caribou Ranch. In later years, band members cited Guercio's purchase of Caribou Ranch, more particularly their realization that Guercio had enough money to purchase Caribou Ranch, as a contributing factor to their disillusionment with him as a producer. They felt he had taken advantage of them financially.: 131 Then on January 23 of that same year, Kath died of an accidental, self-inflicted gunshot wound from a gun he thought was unloaded. Doc Severinsen, who was the bandleader for The Tonight Show Starring Johnny Carson at the time and a friend of the group, visited them after Kath's funeral and encouraged them to continue. According to writer Jim Jerome, the visit "snapped them back" and helped them make the decision to carry on.
After auditioning over 30 potential replacements for Kath, Chicago decided upon guitarist and singer-songwriter Donnie Dacus. While filming for the musical Hair, he joined the band in April 1978 just in time to record the Hot Streets album. Its energetic lead-off single, "Alive Again", brought Chicago back to the Top 15; Pankow wrote it "originally as a love song but ultimately as recognition of Kath's guiding spirit shining down from above".
Concurrently with Chicago's existing career, vocalist Peter Cetera had begun a solo career. He proposed an arrangement with the band where they would take hiatuses after tours to let him focus on solo work (mirroring that of Phil Collins and Genesis), but the band declined. Cetera ultimately left Chicago in the summer of 1985. He soon topped the charts with "Glory of Love" (the theme song of the film The Karate Kid Part II), and with "The Next Time I Fall" (a duet with Amy Grant). Two more songs reached the top ten: a 1988 solo hit called "One Good Woman" (No. 4 U.S.), and a 1989 duet with Cher called "After All" (No. 6 U.S.). In 1992, Cetera released his fourth studio album, World Falling Down, which earned him three hits on the Adult Contemporary charts, including the single "Restless Heart". Cetera's former position was filled by bassist and singer-songwriter Jason Scheff, son of Elvis Presley's bassist Jerry Scheff. Guitarist Chris Pinnick also left the group in 1985, prior to the recording of the band's next album.
The beginning of the 1990s brought yet another departure. Original drummer Danny Seraphine was dismissed from the band in May 1990. Seraphine was succeeded by Tris Imboden, a longtime drummer with Kenny Loggins and former session drummer with Peter Cetera. Imboden made his first appearance on the 1991 album Twenty 1 with a fragment of band's logo, which yielded an eleven-week stretch on the Billboard 200, a peak at No. 66, and the song "Chasin' the Wind" which peaked at No. 39. Twenty 1 would be their last released album of original music for fifteen years.
After finishing their 1994 tour, and after signing with the Warner Bros. Records imprint label Giant Records, they released their 1995 album Night & Day: Big Band, consisting of covers of songs originally recorded by Sarah Vaughan, Glenn Miller, and Duke Ellington. Guitarist Bruce Gaitsch stepped in and joined the band to handle the album's guitar work. The album featured guest appearances by Paul Shaffer of Late Show with David Letterman fame, Aerosmith guitarist Joe Perry, and the Gipsy Kings. Parazaider cited the group's participation in the 1973 television special honoring Duke Ellington, Duke Ellington... We Love You Madly, as key in their decision to record this album. After this big band album, Chicago acquired the rights to their Columbia recordings and reissued them on their own imprint. In early 1995, Keith Howland, who had been a studio musician and stage hand based in Los Angeles, was recruited as Chicago's new permanent guitarist.
In 2004, 2005, and 2009, Chicago toured with Earth, Wind & Fire.
After taking a temporary leave in May 2016, citing "family health reasons", it was announced on October 25, 2016, that Jason Scheff had left Chicago after 31 years. Bassist/vocalist Jeff Coffey, who had been filling in for Scheff during his absence, was promoted to a full-time member. Saxophonist Ray Herrmann, who had previously filled in for Parazaider on various tour dates since 2005, also became an official member at this time after Parazaider retired permanently from the road. Although Parazaider retired from regular touring, he remained a band member.
On February 22, 2017, it was announced that Cetera, Lamm, and Pankow were among the 2017 Songwriters Hall of Fame inductees for their songwriting efforts as members of Chicago. The induction event was held Thursday, June 15 at the Marriott Marquis Hotel in New York City.
Chicago's website stated that in 2017, the band was working on a new album, Chicago XXXVII.
On September 17, 2017, former percussionist Laudir de Oliveira died of a heart attack while performing onstage in his native Rio de Janeiro.
On Wednesday, January 17, 2018, drummer Tris Imboden announced he was leaving the band after 27 years to spend more time with his family. On Friday, January 19, 2018, bassist and vocalist Jeff Coffey announced on his Facebook page that he was also departing from the band due to its heavy touring schedule. Chicago announced that percussionist Walfredo Reyes Jr. was moving over to drums, replacing Imboden. Vocalist Neil Donell, of Chicago tribute band Brass Transit, was chosen as the band's new lead singer and session musician Brett Simons also joined the band as their new bassist. Daniel de los Reyes' return to the percussion position was announced, filling the vacancy left by his brother's move to the drumset.
In May 2018, it was revealed that percussionist Daniel de los Reyes was departing Chicago to go back to his other group, the Zac Brown Band. On Thursday, May 17, 2018, Chicago announced on their official Facebook page and on their Twitter account that "Ray" Ramon Yslas had joined the band on percussion.
In July 2018 the band updated its official web site, and no longer listed Parazaider as a member of the band. Instead he is included on the band's "Tribute to Founding Members". Parazaider had retired from touring previously.
On August 16, 2019, the band announced on their website that they would be releasing their fourth Christmas album, titled Chicago XXXVII: Chicago Christmas, on October 4, 2019. The album has a greater emphasis on original Christmas songs written by the group than their previous holiday albums.
On April 19, 2021, Walter Parazaider released a statement that he has been diagnosed with Alzheimer's disease.
During their 2021 summer tour, Lou Pardini was out for part of August and most of September, with Who keyboardist Loren Gold filling in until Pardini was able to return. On November 15, 2021, Howland broke his arm in an accident and took a leave of absence from the band, with guitarist Tony Obrohta filling in for him at shows. On December 1, 2021, Howland announced he was leaving Chicago after over 26 years, citing the recent accident and lengthy recovery period as bringing about the next phase of his life. The band confirmed Howland's departure, and removed his name from band lineup page on their website. Tony Obrohta officially joined the group to replace Howland in December 2021.
On January 21, 2022, Lou Pardini announced he was departing the band. Loren Gold (vocals, keyboards) appeared with the group on tour filling the role vacated by Pardini starting in January 2022, and on March 2, 2022, Chicago updated their website to list Gold as a band member. On Friday, May 6, 2022, Chicago announced on their website that Brett Simons had departed the band and Eric Baines (bass, vocals) had joined the group. The group also announced plans to release a new album in the summer of 2022. Chicago released the single "If This Is Goodbye" on May 20, 2022. On July 15, 2022, Chicago released Chicago XXXVIII: Born for This Moment. Chicago and Earth, Wind & Fire toured together on the 2024 Heart and Soul joint tour. On March 2, 2025, Carlos Murguia joined the band on keyboards and vocals.
During his discussion of the formation of the band, original drummer Danny Seraphine says he wanted to form a group of talented, skilled musicians, with a horn section, "that could play an inventive mix of rock and jazz.": 47–49 Walter Parazaider told writer, Paul Elliott, "My idea was to make horns an integral part of a rock band." According to James Pankow, Chicago set out to be "basically" a rock and roll band with a horn section. Robert Lamm credits Walter Parazaider and Terry Kath for having the vision of "a rock band with expanded instrumentation." Peter Robb wrote, "The guys had all been influenced by show bands that would come into Chicago playing a variety of music. Those bands always had tenor sax, trumpet and trombone, Loughnane said."
Chicago was deeply influenced by jazz, which culminated on their seventh album. Trumpeter Lee Loughnane holds that the term "jazz rock" was invented because of Chicago's music. When asked why the band didn't continue in its "jazzy improv" direction, Loughnane voiced his opinion that how the songwriters wrote was "materially affected" by changes in payment of royalties by the record companies and by the relatively short airplay time allowed for a song on the radio.
James Pankow has described the group's songwriting process as "organic", where one person comes up with a song and the other members come up with ideas for their parts. Pankow, one of the songwriters for the group, also has typically been arranger for the horn section. Robert Lamm, another of the group's songwriters, sees the group members' contributions to individual songs more as arranging than co-writing, and says his songs were "enhanced" in the process.
Chicago has supported numerous charitable causes throughout the years.
In the 2010s the group had an ongoing partnership with the American Cancer Society. Fans were given the opportunity to bid to sing their song "If You Leave Me Now" with them on stage during their live performances. The proceeds went to the American Cancer Society to fund the Society's efforts to fight breast cancer.
The group gave a benefit performance for Musicians on Call, on Sunday April 23, 2023, held at the Hard Rock Cafe in Times Square in New York City. Musicians on Call is a nonprofit organization that brings live and recorded music to the bedsides of patients, families and caregivers in healthcare settings. The group donated an autographed guitar to the event's live auction and the $6,000 winning bid was made by singer Dionne Warwick. Chicago also did benefit performances for Musicians on Call in 2011, 2012, and 2022.
Upon being renamed from Chicago Transit Authority to Chicago, the band sported a new logo. Its inspiration was found in the design of the Coca-Cola logo, in the attitude of the city of Chicago itself, and in the desire to visually transcend the individual identities of the band's members. It was designed by the art director of Columbia/CBS Records, John Berg, with each album's graphic art work being done by Nick Fasciano. Berg said, "The Chicago logo...was fashioned for me by Nick Fasciano from my sketch."
The album cover series has endured as a cataloged work of art in its own right, described by Paul Nini of the American Institute of Graphic Arts as a "real landmark in record cover design". In 2013, the iconic status of Chicago's album art was featured in a New York art museum exhibit, which centered upon ninety-five album covers completely selected from John Berg's career portfolio of hundreds. Having overseen the design of approximately fourteen Chicago album covers across more than twenty years, Berg stated that this artistic success resulted from the combination of Chicago's "unique situation" and his position in "the best possible job at the best possible time to have that job, at the center of the graphic universe". Berg won the 1976 Grammy Award for Best Album Package for Chicago X, one of four Grammy Awards he won in his lifetime.
As of July 2018, the three remaining active original members of Chicago are Lamm, Loughnane, and Pankow. Parazaider has retired from regular touring but is still considered as a band member, and has appeared with the group during certain events.
The legal hierarchy of the band was illuminated in a July 2022 published interview with Robert Lamm, in which he, Pankow and Loughnane are identified as the "partners" and the rest of the members as "contracted players". According to Lamm, the three partners control what the band does. The decision to record the 2022 album, Born for This Moment, depended largely on the consensus of the three partner members.
For several years, the exact status of Walter Parazaider as a current member or former member was unclear. A 2017 article said Parazaider retired due to a heart condition, but was still "technically" part of the group. Another 2017 article said that Ray Herrmann had become a full-time touring member, but that "Parazaider is still a band member and performs with the group for certain events." According to a 2018 article, Parazaider "officially retired" in 2017. By August 10, 2018, Ray Herrmann was shown as a member of the band, and Parazaider was not, on the group's official website. While Parazaider at times had been referred to as a non-touring member of the group, he did not appear on either of the studio albums released since his retirement, 2019's Chicago Christmas, and 2022's Born for This Moment. In 2021, Parazaider revealed he had been diagnosed with Alzheimer's disease.

Although Rolling Stone reporter Charles M. Young wrote that Chicago was awarded the platinum bar because it was the first band to receive platinum album certification for Columbia Records,[63] this was not the case. Chicago X was certified platinum on September 4, 1976, but Aerosmith's album, Rocks, also on Columbia Records, was certified platinum on July 9, 1976, before it.[65][66] Billboard reported that the platinum bar was awarded in recognition of the group's ten platinum albums.[64] Billboard's account seems more likely in consideration of the two-full-pages advertisement Columbia placed in the June 12, 1976, issue of Record World announcing, " 'Chicago X.' Their tenth platinum album, on Columbia records and tapes."[67] The albums released prior to 1976, however, were not actually certified platinum by the RIAA until 1986.[68] /wiki/Rolling_Stone

Chicago X was certified platinum on September 4, 1976, but Aerosmith's album, Rocks, also on Columbia Records, was certified platinum on July 9, 1976, before it.[65][66] Billboard reported that the platinum bar was awarded in recognition of the group's ten platinum albums.[64] Billboard's account seems more likely in consideration of the two-full-pages advertisement Columbia placed in the June 12, 1976, issue of Record World announcing, " 'Chicago X.' Their tenth platinum album, on Columbia records and tapes."[67] The albums released prior to 1976, however, were not actually certified platinum by the RIAA until 1986.[68] /wiki/Rolling_Stone
