The aptly-named Sleep from visual and sonic artist Thaniel Ion Lee admirably lives up to its name in a way that hypnotizes and blankets the listener. Comprised of one long and unbroken drone, the 30-minute track is a deep and vibrating pulse that blends seamlessly into the background, humming and throbbing along in the periphery of your conscious without posing much, if any, distraction. In this sense, the track is an ideal aid for the slumber impaired. This is absolutely the least exciting thing to listen to, but that’s exactly the point here — you lose yourself totally in the pulse, like the low mechanical purr of a distant machine. It’s easy to drift into the void listening to this, which makes this recording a success.
