Composer Milton Babbitt died yesterday at the ripe old age of 94. I have always adored his piece Ensembles For Synthesizer, composed from 1962-64 on the guargantuan RCA Mark II synthesizer for which he was an official composer/consultant. I include that piece here from the 1967 album New Electronic Music from Leaders of the Avant-Garde which is a toweringly great slab of classic experimental music. Seek it out !

And because it’s so totally great, here is the John Cage piece from the same LP: Variations 2 as performed with brutal precision on amplified piano by the great David Tudor.
