List of Chicago band members

In 1974, percussionist Laudir de Oliveira was added as an eighth member of the band after contributing to Chicago VI and VII as a guest musician.

[4] The band briefly considered breaking up after Kath's death, but ultimately chose to continue and added Donnie Dacus as his replacement in April 1978.

[8] In late 1981, after being dropped by Columbia Records, the band started working with David Foster as its new producer, who introduced keyboardist, guitarist and vocalist Bill Champlin to the lineup.

[16] Bruce Gaitsch initially filled in on guitar, including the recording of 1995's Night & Day: Big Band,[17] before Keith Howland was hired as Bailey's replacement in January 1995.

[27] In October 2016, Scheff also left the band after a five-month leave of absence due to "family health issues", with his replacement Jeff Coffey taking over on a permanent basis.

[30] Reyes subsequently switched from percussion to take over Imboden's role on drums, while Coffey was replaced by vocalist Neil Donell and bassist Brett Simons.

[34] 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.

Loren Gold, who had substituted for Pardini in August and September 2021, began appearing with the group on vocals and keyboards for tour dates starting in January 2022.

[38][39] On Friday, May 6, 2022, Chicago announced on their website that Brett Simons had departed the band and Eric Baines (bass, backing vocals) had joined the group.
