4.1 + A thorough takedown of American pop culture of the 1960s and an important check against the generally utopian portrayal of hippie culture. Frank Zappa exposes all of America's warts, from the lame to the downright reprehensible. I especially love the whacked out doo wop of "Go Cry..." The last stretch of musical montages are among the whackiest and most avant garde of any rock record.
