4.2 + Hippies enjoy a generally sunny reputation within the American psyche, so it's refreshing to hear their thorough takedown on this record. Zappa exposes the hypocrisy and half-baked humanism behind the flower power movement on songs like "Who Needs the Peace Corps?" and "Flower Punk." But there's plenty of satire to dish all around and Zappa is sure to throw in some barbs aimed at the older generation on "Mom & Dad" and "Bowtie Daddy." The music teems with psychedelic tropes - distorted guitars, reverb-laden vocals, strange sound collages - both mocking and outshining the "serious" psychedelic musicians of his day.
