This 1986 completely improvised one-man show at the Aquarius Theatre in Los Angeles is the essence of Bobby McFerrin's magic. Using only his pliable voice and his body as percussion instrument, McFerrin lets his fertile imagination and vast musical knowledge run in free-association overdrive, dipping into jazz tunes, arias and Beatle songs along the way. Wayne Shorter joins him for a duet on Miles Davis's "Walkin'". Added to this remarkable concert are the two videos that McFerrin made in support of his "Simple Pleasures" album, "Don't Worry, Be Happy" and a tour-de-force "Good Lovin'". Total running time is 55 minutes.
