B.B. King is one of the unquestionable masters of the electric guitar, and he even perfected a few techniques that we now take for granted. His vocal vibrato, smooth and fluid bending, silky sound and perfect phrasing brought the art of the guitar solo to a whole new level. He also brought harmonic sophistication to the blues by adding brass and strings to his band, but still sounds just as good in a stripped down context, like on the classic album Live At The Regal (1965).
