This album launched Barry Harris on what has become one of the most respected, long-lasting, and influential careers in modern jazz. But in one sense it was a sequel to the most hugely successful live jazz recording of its period, the 1959 Cannonball Adderley Quintet in San Francisco. The club was the same; so was the record label and producer. It was just seven months later; Cannonball and band were back in town--but this was their night off, and although this was their rhythm section, the featured pianist was quite different. In place of superfunky Bobby Timmons, there was Harris, then a brilliant disciple of the Bud Powell school, newly but permanently enticed out of Detroit and into the post-bop mainstream.
