How can you make a list of best bands from Chicago and not include the band named after the city (originally named after the Chicago Transit Authority)? At any rate, these guys were the top American rock band during the 1970s before they became a soft-rock machine in the early 1980s. The band has sold more than 38 million units in the U.S., with 22 gold, 18 platinum, and eight multi-platinum albums. The band also has had five No. 1 albums and 21 top-ten singles.
