Except for an '80s drum-machine pop vocal misfire, the rest of the album is solid, including tape music concrete pieces dating to the pre-Moog early '60s, right up to some lovely recent songs for piano+theremin, with stops along the way for some space-age Shakespeare, a bit of operatic vox, and more future-jazz courtesy of a sax-enhanced version of the traditional black American lament "Sometimes I Feel Like a Motherless Child".
I digitized an 7" ep of Deutsche's that I bought at a used shop ages ago that apparently was meant to accompany a book about electronic music that Deutsche wrote in the '70s. Each side is only 5-6 minutes long, but it's plenty fun. Side a features Deutsche's narration as he demonstrates basic tape functions, then creates a nutty tape loop. Side b features narration-free instros, including some really wacked-out tape loopiness and a wicked bit of Moog funk.
