The American rock band is one of the longest-running and most successful rock groups. They have been one of the world’s best-selling groups of all time, having sold more than 100 million records.

Since the beginning of the group’s formation, Chicago has flown under the radar. Regarding both albums and singles, they’re not far behind the Beach Boys either. In 1971, four years after their formation, the group was the first rock act to sell out Carnegie Hall for a week.
