John Mayall & the Bluesbreakers
Mayall's personnel tended to overshadow his own considerable abilities. Only an adequate singer, the multi-instrumentalist was adept in bringing out the best in his younger charges (Mayall himself was in his thirties by the time the Bluesbreakers began to make a name for themselves). Doing his best to provide a context in which they could play Chicago-style electric blues, Mayall was never complacent, writing most of his own material, revamping his lineup with unnerving regularity, and constantly experimenting within his basic blues format.
