Mendelbaum was active in the late '60s and early '70s in San Francisco. Singer, guitarist, and main songwriter Chris Michie would become a studio musician (he recorded with the Pointer Sisters and Van Morrison) and solo artist, while drummer Keith Knudsen would later join the Doobie Brothers. Bassist Tom LaVarda, sax player George Cash, and organist Ronnie Page (heard on the live cuts from the Matrix on the second disc, later replaced by J.D. Sharp) complete the group.
