AMG REVIEW: Although R. Stevie Moore and Victor Lovera spent most of the early '70s creating sweetly catchy soft rock tunes and quirky pop-rockers, Moore in particular has always had an experimental streak a mile wide. Recorded in 1971 and 1972, when Lovera and Moore were in their late teens and early 20s, All Twenty Minutes is like a head-on collision between Frank Zappa in his Lumpy Gravy phase, and John Cage at his most random and anti-musical. This is not music at all, but eight lengthy pieces of what Moore quite rightly terms "extreme audio torture." Snatches of random conversation, stoned-sounding babbling, blasts of feedback and amelodic noise that even Throbbing Gristle would find excessive, and the occasional snippet of a recognizable Lovera or Moore composition from this period (bits of a solo acoustic demo of Moore's "Radios" crop up on "Two-Tone Part 1") are stitched together Frankenstein-like into an often-overwhelming whole. This one's for the brave.
