Started by Jonathan More and Matt Black of cut-'n'-paste gurus Coldcut, the Ninja Tune label has always followed a quirky inner logic that bypasses mainstream dance music sounds (house, trance, and big beat) for eclectic explorations of electronic beat science. The Ninjas continue to defy expectations with Xen Cuts, a three-disc compilation celebrating the label's tenth anniversary. Instead of stuffing the collection with high points from their stellar back catalogue, the London-based label coaxed two CDs of new material from their diverse roster of wax scratchers, knob twiddlers, and rhyme spitters. And the third disc is subtitled "Missed, Flipped & Skipped" and gathers unreleased gems, forgotten B-sides, and rare promo-only tracks. The breadth and depth of this survey is incredible and far too extensive to list here. But know this: The set includes selections of cutting-edge American rap (Saul Williams, Mike Ladd, Blackalicious), world hip-hop (Russia's DJ Vadim, the U.K.'s Roots Manuva), acid jazz (Up, Bustle and Out, DJ Food), jazzy down-tempo (Cinematic Orchestra, Amon Tobin), turntable pastiche (Coldcut, Kid Koala), experimental techno (Squarepusher, Neotropic, Luke Vibert), and much more -- absolutely essential listening for headz of all stripes.
