The 154th Roadhouse investigates the mystery of a number pair: 6 and 3. It lies at the heart of the blues, but it's simplicity is deceptive. Son Seals, Johnny Winter, Robert Cray, Robert Johnson, Michael Bloomfield - all have mastered the essence of the blues that lies in these numbers: 6 strings and 3 chords. It's a mystical blues guitar edition of The Roadhouse, another hour of the finest blues you've never heard.
