A barricade of noise will be erected at the Barbican as the American Pioneers series continues with Glenn Branca's Electric Guitar Swarm. Branca will be playing some specially commissioned work with his dozen or so six-string cohorts. The frenzy is preceded by two free shows in the foyer; Ben Neill plays with Helmet's Page Hamilton at 5pm, while Marc Ribot fuses Cuban rhythms and rock and roll at 6.30pm.
