Ambient Music for Sleep consists of two 30-minute tracks, each a swirling, not-quite-music soundscape suggesting the subtle motions of cloud fields. According to its liner information,
Ambient Music for Sleep is embedded with "specific inaudible sound frequencies" that help you fall asleep easily and wake up rejuvenated. It's the work of
Dr. Jeffrey D. Thompson, who composed the pieces after years of sleep and psychotherapeutic research. The recording is a product of Gaiam, a Boulder, Colorado-based lifestyle's retailer.
