In his review for AllMusic review states Arwulf Grenier wrote, "This studio session contained many elements associated with a live gig: the work took place during regular nightclub performing hours, the improvisations were mostly extended, and there were no alternate takes. A remarkable freshness and spontaneity prevailed throughout the session".[3]
