On his fifth album, London's elusive Zomby scatters his signature palette of crystalline synths, haunting minor keys, and 8-bit crunch across backbeats that range from Chicago house to acid techno to hip-hop. Let's Jam!! commences with a surf-themed set of rolling bass waves and beach-ball-round kick drums ("Surf I," "Surf II," "Acid Surf") before swerving into 140 BPM territory, where purple melodies frolic over trap drums. "Peroxide" is particularly fine, a gangsta-rave epic of wistful video-game synths, chipmunked vocals, and early '90s nostalgia.
