Max Roach's final recording with his all-percussion group M'Boom is a live set recorded at the long defunct S.O.B.'s in New York City. Utilizing a vast array of instruments, including vibes, marimba, xylophone, conga, and timpani, among others, Roach and his band offer engaging interpretations of originals written by bandmembers, and standards along with jazz compositions by others and at least one surprise, while the personnel often varies greatly from one track to the next, ranging from solo to octet.
