Chicago

Chicago are an American rock band formed in Chicago, Illinois, in 1967. The group was initially billed as The Big Thing before calling themselves the Chicago Transit Authority in 1968, and then shortening the name in 1969. A self-described "rock and roll band with horns", Chicago's songs often combine elements of classical music, jazz, R&B, and pop music. To date, Chicago have sold over 40 million units in the U.S., with 23 gold, 18 platinum, and eight multi-platinum albums. They have had five consecutive number-one albums on the Billboard 200 and 20 top-ten singles on the Billboard Hot 100. In 1974 the group had seven albums, its entire catalog at the time, on the Billboard 200 simultaneously. The group has received ten Grammy Award nominations, winning one for the song, "If You Leave Me Now". The group's first album, Chicago Transit Authority, released in 1969, was inducted into the Grammy Hall of Fame in 2014. Chicago were inducted into the Rock and Roll Hall of Fame in 2016.
