Sweet Valley is a Bermuda-Triangle-like place where cannabis crumbs, spilt beer, record dust and that mysterious shit you had to blow out of game cartridges all collect as if pulled by some gigantic junkyard magnet. It is a blood pact between two brothers, Nathan (of Wavves) and Kynan Williams gone awesomely off the rails. Welcome to Sweet Valley-hi. You can be sure of nothing here. So Serene is a single 27-minute track that shifts through ideas relatively quickly. There's rarely a dull moment as this thing is packed with fascinating samples, video game sounds and synths aplenty.
