About
Chicago is an American rock band formed in Chicago, Illinois, in 1967. Self-described as a "rock and roll band with horns", their songs often also combine elements of classical music, jazz, R&B, and pop music. Growing out of several bands from the Chicago area in the late 1960s, the original line-up consisted of Peter Cetera on bass, Terry Kath on guitar, Robert Lamm on keyboards, Lee Loughnane on trumpet, James Pankow on trombone, Walter Parazaider on woodwinds, and Danny Seraphine on drums. Cetera, Kath, and Lamm shared lead vocal duties. The group initially called themselves The Big Thing, then changed to the Chicago Transit Authority in 1968, and finally shortened the name to Chicago in 1969. Laudir de Oliveira joined the band as a percussionist and second drummer in 1974. Kath died in 1978 and was replaced by several guitarists in succession. Bill Champlin joined in 1981, providing vocals, keyboards, and rhythm guitar. Cetera left the band in 1985 and was replaced by Jason Scheff. Seraphine left in 1990 and was replaced by Tris Imboden. Although the band's lineup has been more fluid since 2009, Lamm, Loughnane, and Pankow have remained constant members. Parazaider "officially retired" in 2017.
