B.B. King sometimes gets pegged as "the major pentatonic guy," but on his definitive live recording from 1964, "Live At The Regal," it's his flawless weaving together of major and minor pentatonic sounds that packs such an emotional wallop. That, along with great material, a crack band, sensational vocals and an ecstatic crowd that hangs on B.B.'s every word. Mixing and matching the two pentatonic sounds lends each one far greater impact that it would have used on its own.
