Musical purists take note: if your idea of what constitutes jazz ends with the work of John Coltrane and Miles Davis, stop reading now. This collection is an unconventional one, to say the least. Violins, samplers and even (gasp!) turntables are all tangentially linked under the hierarchy of jazz, with new-school acts like pianist Matthew Shipp and bassist David S. Ware sharing equal space with Def Jux MC El-P and Anti-pop Consortium. Skronks, scratches and squiggles of noise abound; this is hardly the cool jazz of Blue Note's peak, but something more closely aligned with the cosmic chaos of Sun Ra's Saturn Records imprint.
