Random You Tube find - Alfred Schnittke's Concerto for Electric Instruments

I love Schnittke, but I'd never heard of this piece until I saw it in the Elitist Classical subreddit. Composed in 1960, but apparently unfinished (and otherwise unrecorded), it's more or less a concerto for theremin with the other instruments imitating an orchestra, more imitation than original electronic sounds. Nonetheless, an interesting listen.
