In Session, recorded in 1983, is the only known recording of Albert King and Stevie Ray Vaughan performing together. Its long-overdue commercial release (the album didn't come out until 1999) stands as a fitting tribute to the genius of two of the greatest musicians ever to have played the blues on electric guitar.

Anyone who's witnessed a much-anticipated jam session only to be disappointed with each participant deferring to the other, the end result being that neither ever got out of first gear will welcome this pairing of two giants of blues guitar. Albert King and Stevie Ray Vaughan obviously shared a mutual admiration, but it simply wasn't in either one's makeup to a) be intimidated or b) take a backseat to anyone. Not without kicking up a little dust.
