Jean-Jacques Perrey - Prélude au Sommeil (1957)

Jean-Jacques Perrey - Prélude au Sommeil, mono LP published by Institut Dormiphone, France, 1957

Jean-Jacques Perrey's first solo LP, Prélude au Sommeil, or Prelude to Sleep, consisted of 2 side-long tracks of ambient electronic music played on George Jenny's Ondioline. The disc is actually a private release from a so-called Institut Dormiphone (also Procédés Dormiphone), aka Perrey himself, in an edition of 500 copies, according to official biographer Dana Countryman. The music is intended as sleep-inducing and tranquilizing for use in mental hospitals.
