t's not a club, but it's one to add to your list. Founded by Willie Dixon, the Blues Heaven Foundation promotes and pays homage to Chicago's musical legacy. The foundation's legendary 2120 S. Michigan address housed the Chess Records Studio from 1957 to 1967 and hosted recording sessions for everyone from Aretha Franklin to Etta James and Chuck Berry. (The venue is so rich in musical history that The Rolling Stones have a track called "2120 S. Michigan Avenue" on their 12x5 album.) Tours, offered to the public Monday-Saturday, allow a glimpse into Leonard and Phil Chess' former office, the Main Studio where legends belted it out on record, the original sound-proofing room and the rehearsal studio.
