Review: The sheer volume of New York maverick DJ Spider's back catalogue is as intimidating as the picture of the man himself holding a machete in the studio, but it's a rich and unpredictable treasure trove of leftfield techno. He makes an appearance on Thema with a record typically diverse in its make up. The opening track "Throwing Hairs" is a masterful trip through atmospheric, organic soundscapes with submerged ecosystems of sound rippling around deathly simple kick n hi hat pattern. His own rework of "Extropy" features similar smudged textures underneath, but the sweet nature of the chords makes for a killer foil to the murk. "The Final Revolution" gets into a tougher frame of mind, placing plenty of emphasis on the low end and letting fly with some seriously dishevelled percussion. "Distress Signal" is oppressive in its sense of desolation, all icy winds blowing into a kick propelled nothingness.
