The Brecker Brothers were a jazz fusion music duo consisting of siblings Michael and Randy.
Randy, the older brother, became famous as an original member of the group Blood, Sweat & Tears.
Michael first appeared on record supporting Randy on his solo debut album, titled Score, which was released in 1969.
Other notable appearances include Parliament's Mothership Connection and the debut album of the Japanese fusion group Casiopea.
The recordings were made during a special appearance of the brothers with members of the Saturday Night Live Band at Zappa concerts at the Palladium in December 1976.
