The cool cats that helped introduce you to the alt-hop and experimental turntablism of Amon Tobin, DJ Food, Cut Chemist and Kid Koala sure know how to celebrate in style. To usher in two decades of left-of-center beats and cross-fader trickery, pioneering label Ninja Tune just released Ninja Tune XX: 20 Years of Beats and Pieces, a 6-CD collection (more than 100 songs!) that also includes a 192-page book, six 7-inches and two 12-inches. God bless you, Coldcut. See what the ruckus is all about at www.ninjatune.com. (Matt Tapia)
