2lous is Lou Bunk and Lou Cohen, co-directors of the Opensound concert series in Somerville, Mass., USA. Please see www.opensound.org.OpenSound is a monthly concert series that explores improvised music, bringing artists from disparate backgrounds together for unique events in Somerville MA. The process of improvisation combines the distinctive voices of its individual performers. The music that results is often surprising, beautiful, ugly, and dynamic. It is 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.
