Chicago is a jazz-fusion band formed in 1967 in Chicago, Illinois. The band began as a politically charged, sometimes experimental rock band and later moved to a softer sound, becoming famous for producing a number of hit ballads. They had a steady stream of hits throughout the 1970s and early 1980s. Second only to the Beach Boys, Chicago, in terms of singles and albums, is one of the longest running and most successful U.S. pop/rock and roll groups.
