"Every guitarist who bends or vibratoes a string to make it sing owes a debt to B.B. King. With influences as diverse as T-Bone Walker, Charlie Christian and Django Reinhardt, the late guitarist turned the blues world upside down in 1952 with “3 O’Clock Blues.” Almost overnight, the harmonica was supplanted as the primary solo instrument in blues, as guitarists scrambled to imitate B.B.’s soloing style, especially in Chicago."
