Zs + Excepter + Mick Barr + Silk Flowers

Starting out as a hyperfocused avant-chamber outfit, Zs has evolved into a more aggressive and open-ended beast. The band, which draws on noise, art rock and cutting-edge improvisation, is playing behind a mind-bending new Social Registry full-length, New Slaves. Helping out are dubby, kitschy beat-collagists Excepter and postmetal guitar marvel Mick Barr.
