Warner Jepson's album Totentanz. Available here on LP.
Considered as the first piece of electronic music to accompany a ballet, Totentanz is the arrestingly abstract and mightily expressive result of Warner Jepson’s experiments with tape and Don Buchla’s groundbreaking synthesizer, the Buchla 100. Totentanz, originally self-released in 1972, reveals a composer relieved of convention.
