Limited vinyl LP pressing. When we last heard from Pietro La Rocca, he was honing his inscrutable craft with the unflinchingly great Sicilian ensemble, Oper'azione Nafta, whose Cavuru forged the skree of High Rise with the yelp of Sun City Girls. On Manifesto Rumoratorio, La Rocca teams up with ex-pat Polish vocalist Patrycja Stefanek with the results running the gamut from agog to agape. Utilizing a small array of gadgets (Walkman, delays, toys, and tapes) in conjunction with voice and guitar, the results simmer in an ardor of abstract improvisational babble-think Vetza/Joe Potts (LAFMS), Jim French/Diamanda Galás on Metalanguage, Joan La Barbara/Bruce Ditmas on Wizard Records, or Suckdog. Polarizing? Sure, but like the deep end of the pool, it's great once you get in. Produced by Siltbreeze majordomo Tom Lax, in conjunction with the Oley Freindschaft Guild of Braucherei Practitioners and the Guild of Urglaawe Braucherei and Hexerei Practitioners, Manifesto Rumoratorio possesses a language understood by, if not hundreds, then literally dozens of rabid, abstract-clatter-wanters. The rest of you? Bring a coat, it might get chilly.
