John Mayall, the British blues musician whose influential band the Bluesbreakers was a training ground for Eric Clapton, Mick Fleetwood and many other superstars, has died. He was 90. He is credited with helping develop the English take on urban, Chicago-style rhythm and blues that played an important role in the blues revival of the late 1960s. A statement on Mayall's official Instagram page says he died Monday at his home in California. Though Mayall never approached the fame of some of his illustrious alumni, he was still performing in his late 80s, pounding out his version of Chicago blues.
