"Weasels can make for difficult, incoherent listening, especially at first. But there is a certain logic behind the band's accomplished genre-bending and Zappa's gleefully abrupt veering between musical extremes; without pretension, Zappa blurs the normally sharp line between intellectual concept music and the visceral immediacy of rock and R&B. Zappa's anything-goes approach and the distance between his extremes are what make Weasels Ripped My Flesh ultimately invigorating".
"A fascinating collection of mostly instrumental live and studio material recorded by the original Mothers of Invention, complete with horn section, from 1967-1969, Weasels Ripped My Flesh segues unpredictably between arty experimentation and traditional song structures ... Zappa's anything-goes approach and the distance between his extremes are what make Weasels Ripped My Flesh ultimately invigorating; they also even make the closing title track - a minute and a half of squalling feedback, followed by applause - perfectly logical in the album's context".
