Best BLUES album ever,IMHO:

Buddy Guy, "A Man and the Blues," Vanguard, appx 1966(?)

This is a rare "solo" recording by Buddy during the years he was teamed with Junior Wells. Actually, it is really a set of duets with pianist Otis Spann, normally a member of Muddy Waters' band, backed with bass, drums (Fred Below), 2d guitar (Wayne Bennet) and, on some numbers, a horn section. There are a couple of nice lively uptempo numbers (notably "Mary Had a Little Lamb"), but what makes this album really special are the deeply spooky slow blues, where the interplay between the two main instrumenalists is simply unbelievable & downright scary.
