Chicago - Rock Legends

Chicago is an American rock band formed in 1967 in Chicago, Illinois, calling themselves the Chicago Transit Authority in 1968 before shortening the name in 1969. The self-described “rock and roll band with horns” Chicago is one of the longest-running and most successful rock groups, and one of the world's best-selling groups of all time, having sold more than 100 million records in 1971, Chicago was the first rock act to sell out Carnegie Hall for a week.
