The Electrosoniks (Tom Dissevelt & Kid Baltan) - Electronic Music. (1962)
My favorite of the dozen or so generically-titled electronic releases of the early 60s.
Fun trivia - The UFO sound of the opening seconds from "Moon Maid" were lifted by the novelty group, The Ran Dells two years later on their mega-hit, "the Martian Hop." They were heralded for years for their "innovative" early-electronic sounds but were perhaps one of the earliest examples of illegal sampling. (Though, notably - Buchanan And Goodman beat them by several years in 1956 with the equally-successful "The Flying Saucer Pts 1 & 2")
Also - Jean-Jacques Perrey visited Dissevelt and Baltan during the production of this LP and cited them as an inspiration for his move to electronic music.
