In 1983, when legendary blues guitarist Albert King, then age 60, was joined by his disciple Stevie Ray Vaughan, then age 29, on a Canadian sound stage for the live music TV series In Session, magic took place. Albert King with Stevie Ray Vaughan In Session is not simply a television program: it's a summit of two master musicians. The only known recording of King and Vaughan performing together, this is the concert that blues fans in general, and Stevie Ray Vaughan fans in particular, have been waiting for.

The audio recording of the performance went on to sell more than 325,000 units from two releases: the first in 1999, the second in 2009. On November 9, 2010, Stax Records, a division of Concord Music Group, released In Session as both a DVD and a deluxe DVD/CD combination.

An hour and 45 minutes, approximately, was taped of the two. What will thrill viewers who are fans of the blues, players of the blues, and who adore SRV, is that the televised concert includes at least one SRV tune — "Texas Flood" — that was not included on either of the two CD releases of the session.

The innovative Canadian television series was conceived with the intention of pairing musicians who were related stylistically, but seldom had an opportunity to play together. Albert King wasn't sure whom he'd been booked to jam with on December 6, but he recognized the young Texan immediately — not as fast-rising star Stevie Ray Vaughan, but as Little Stevie, the skinny kid who'd been coming around and eventually sitting in every time Albert passed through Austin.

Stevie idolized Albert, as did many other "modern" electric axe-men. Albert may have been overshadowed by B.B., but Jimi Hendrix, Keith Richards, Eric Clapton, Robbie Robertson, Mick Taylor, and Joe Walsh — all of them listened to him, listened again and again, and were heavily influenced by his style.

At the time of the taping, the buzz may have been around Stevie, but Albert was clearly in charge of the music. Earlier in the year, in May, David Bowie's "Let's Dance" featuring Stevie at his blistering Albert King-inspired best, hit the top of the Billboard pop singles chart; in June, SRV's debut album Texas Flood came out, and MTV put "Pride and Joy" into their rotation. He never looked back.

During their performance, Albert ruled over the proceedings like a benevolent father, retaining control while allowing his guest loads of solo space in which to display his awesome command of the electric guitar. The interplay between the two blues masters is uncannily empathetic, and Albert's fans will find special pleasure in hearing him play rhythm parts at such length. Aside from SRV's two vocals — "Pride and Joy" and "Texas Flood" — all the other tunes are from Albert's repertoire. Viewers have the ineffable treat of seeing Albert King perform "Born Under a Bad Sign," his trademark blues hit, as well as "Call It Stormy Monday."

Sadly, King and Vaughan would not share a stage together ever again. Vaughan, 31 years King's junior, died in a helicopter crash in the fog on the way back from a concert in 1990. King outlived him by two years, dying of a heart attack in 1992. They didn't meet often, and their careers took different paths. But we can all be grateful for that one long day in a television studio when sparks flew and this timeless performance was forever captured.
