Polygon Window – Surfing On Sine Waves

Originally released in 1993 as only the second LP in Warp’s genre-shaping Artificial Intelligence series, this album marked Richard D. James’ first full-length under any alias. Now reissued for 2025 in an expanded edition, the album is finally given the kind of retrospective treatment its cult status deserves. Long overshadowed by Selected Ambient Works and Classics, it showed James was moving from rave-fuelled acid techno toward the more intricate, atmospheric forms that would define his mid-90s output. The original nine tracks remain as striking as ever. The icy propulsion of ‘UT1-Dot’ is an archetype of industrial-tinged techno, while ‘If It Really Is Me’ shows James’ flair for melody, pairing jittery piano with wistful atmospheres. ‘Quino-Phec’, a gorgeous closer, has the alien ambient beauty that would soon permeate on SAW II. The more abrasive cuts like ‘Quoth’ and ‘Untitled’ may sound raw by today’s standards, they carry the energy of a scene still inventing itself. The expanded edition adds three tracks from the ‘Quoth’ EP in ‘Iketa’, ‘Quoth (Wooden Thump Mix)’ and ‘Bike Pump Meets Bucket’. Surfing on Sine Waves is an important artifact of early IDM history and a deeply listenable, imaginative record. It embodies James’ knack for fusing alien sound design with haunting familiarity.
