"The full version, Sleep, is intended to actually send us to sleep, but From Sleep is a one-hour offshoot during which we're supposed to stay awake. Richter plays piano, organ, synths and low-thrumming electronics; the American Contemporary Music Ensemble adds soft-hewn vocals and strings. It's a warm, slow-moving daydream with no sharp edges and a self-consciously hazy sound, as if recorded next door or underwater".
