(MUSIC) Wooden Octopus Skull Experimental Musick Pfestival reaches a sick peak with these sonic shit-stirrers. John Wiese churns out a cornucopia of extreme frequencies in corrosive spasms. In his aural universe, mysterious sounds bloom and fade unexpectedly, keeping listeners constantly on edge. Survival Research Laboratories sound designer GX Jupitter-Larsen (AKA the Haters) generates dense cauldrons of noisy misanthropy that paradoxically renew your zest for life. Imagine a battle royal of trash compactors—then stuff your ears with cotton balls. (Re-bar, 1114 Howell St, 233-9873. 8 pm, $10 adv/$12 DOS, 21+.) DAVE SEGAL
