Recording with a sextet at the New York jazz club Sweet Basil in August 1977, McBee's band included Chico Freeman on reeds, Dennis Moorman on piano, Joe Gardner on trumpet, Steve McCall on drums, and Famoudou Don Moye on percussion. Two complete albums of music were released by Enja Records from this engagement, the ground breaking recordings Music From the Source [1978] and Compassion [1979].

"Few groups today sound as fresh, generate as high an emotional charge, or leave as lasting an impression as McBee's sextet," Chris Albertson wrote upon the release of these recordings. "It is as if each member were a unique piece of a puzzle, carefully placed to complete precisely the breath taking picture intended. The music is adventurous enough to satisfy any aural daredevil who has not completely lost his or her sense of beauty, yet all the basic jazz values have been preserved with due reverence." - Chris Albertson
