The album incorporates (and mocks) the "clean cut" act Carlin performed on The Ed Sullivan Show on its "AM" side (in monaural), while featuring the counterculture material he was becoming known for on its "FM" side (in stereo with Carlin on the left channel and the audience on the right). Carlin's official website refers to the album as a sort of comedy concept album and says that it "marked Carlin's metamorphosis from straight-laced to hippie, intentionally embracing the growing counterculture."[2]
