B.B. King's guitar solo on The Thrill Is Gone demonstrates his theory that every note must mean something — King famously said he could not play chords and sing at the same time so every note he played had to carry the weight of the whole band. His vibrato, achieved by shaking the entire guitar neck, is the most imitated in blues history, and his guitar Lucille became one of the most famous instruments in popular music.
