OPENSOUND: Improvised and Experimental Music

It s not uncommon to hear music made of electronic crackles, noisy multi-phonics, gurgling, hissing, quiet vocalized gibberish, atonal noodling, bowed metal, blowing sounds, post-everything harmony, and a thousand shades of hullabaloo." It's at 7:45 p.m. Saturday at Third Life Studio in Union Square.
