We take a tour of Chicago’s 2120 South Michigan Avenue, home of Chess Records. The label was formed by two Polish immigrants, Phil and Leonard Chess, and its musical history is rich with soul, R&B, gospel, and rock music. The sounds in this week’s show include performances from Muddy Waters, Howlin’ Wolf, and Chuck Berry and some of the contract recordings out of New Orleans…Bobby Charles, Eddie Bo, and Earl King. Simply divine R&B coming your way, from the very earliest to the later sounds of Sugar Pie DeSanto and Fontella Bass…
