Rather than just rewrite the liner notes that accompanied this I have just copied and pasted them in full, the story behind this is all there and reads as follows. As early as in the late ’60s, Frank Zappa was already planning a big box called The History & Collected Improvisations of the Mothers of Invention. Among the discs in the collection (it has been reported as a 12-record set, then a 10-LP set and later a nine-disc set) is The Weasel Music. Some tracks from this big box found their way to Weasels Ripped My Flesh in 1970. According to one review on the internet, “This is Zappa’s most avant garde work. If Ornette Coleman, Albert Ayler and Peter Brotzmann got together and made a rock album, it would sound like this.” The wikipedia notes: “Weasels Ripped My Flesh mostly captures the Mothers on stage, where they employ frenetic and chaotic improvisation characteristic of avant-garde free jazz.” The Weasel Music Acetate would fit right at home on Weasels Ripped My Flesh.
