It was the soundtrack that never was. In 1969 Frank Zappa and the Mothers of Invention recorded the album, “Uncle Meat.” Mostly an instrumental album, the few lyrics are basically inside jokes. The science fiction film for the soundtrack was never completed. Critics praised the album for its creative aspects in editing, overdubbing, and its conceptual sound.  Released by Bizarre Records, an original copy with blue record labels is worth up to $200.00 today. Re issues have brown labels and worth no more than $15.00.
