Masked Turnip compiles songs and tunes that Frank Zappa was involved with in various ways before he became known as the leader of the Mothers Of Invention. For several years prior to the Mothers becoming MGM-Verve recording artists, Frank was associated with the Pal Recording Studio, whose owner and operator was Paul Buff. It was here, in Cucamonga, under Buff's tutelage, that Frank learned how to use a studio to create music, as opposed to simply writing dots on paper. Frank later bought the studio from Buff and renamed it Studio Z, but all of the contents of this compilation were recorded before that happened. Frank's contribution to these tracks was either as musician, singer, writer or producer or a combination of some or all of these roles.
