OpenSound is a monthly concert series that explores improvised music, bringing artists from disparate backgrounds together for unique events in Somerville. 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, bowed metal, blowing sounds, and a thousand shades of hullabaloo. You may also hear buzzes, clicks, wooshes, and bleeps cohabitating in a bizarre galaxy of pitch and spectra!
