OK, here's a REAL GEM:
"Electronic Music Winners" - First recordings of winning works from the ISCM International Competition (Columbia/Odyssey), 1976 album of works from '73 and '74.
Includes 7 short works by Cann, Gressel, Kreiger, Lansky, Semegen, Wright and Zur.
Everything on here is great. The most stunning, I thought, was the 18-minute "mild und leise" by Paul Lansky. Sounded kind of like Leonard Rosenman writing for synthesizers. Gorgeous sustained chords which gradually change timbre and rhythm.
Does anyone know this album? It's killer.
EDIT: Radiohead sampled the piece I was discussing:
