Chicago is an American rock band formed in 1967 in Chicago, Illinois. The original members included Walter Parazaider (woodwinds), Terry Kath (guitar), Danny Seraphine (drums), James Pankow (trombone), Lee Loughnane (trumpet), Robert Lamm (keyboards, vocals), and Peter Cetera (bass, vocals).
The band's early sound was a fusion of rock, jazz, and soul, and their debut album, "Chicago Transit Authority," was released in 1969. The album received critical acclaim and included the hit singles "Does Anybody Really Know What Time It Is?" and "Beginnings."
In the 1970s, Chicago continued to release successful albums and singles, including "25 or 6 to 4," "Saturday in the Park," and "If You Leave Me Now." The band's sound evolved to incorporate more pop and ballad elements, and they became known for their distinctive horn section.
In the 1980s, Chicago experienced some lineup changes and a decline in popularity, but they continued to tour and release albums. They had a resurgence in the 1990s with the release of their album "Chicago XXX," which featured the hit single "Feel."
Over the course of their career, Chicago has sold over 100 million records worldwide and has been inducted into the Rock and Roll Hall of Fame. They continue to tour and perform today with a lineup that includes original members Lamm, Loughnane, and Parazaider.
