Guitarist was contemporary of blues great Muddy Waters.
Magic Slim, a younger contemporary of blues greats Muddy Waters and Howlin' Wolf who helped shape the sound of Chicago's electric blues, died on Friday. He was 75.
Manager Marty Salzman said the musician had health problems that worsened while he was on tour several weeks ago in Pennsylvania.
Magic Slim and his backing band, the Teardrops, performed a no-holds-barred brand of Chicago-style electric blues, led by his singing and guitar playing, and were regulars on the music festival circuit.
Slim's given name was Morris Holt. He established himself in Chicago's thriving blues community in the 1960s, but more recently lived in Lincoln, Nebraska.
