Totally Thames: Bascule Chambers by Iain Chambers

Bascule chambers are the huge underground holes beneath a bridge into which the counterweights of its road section sink when the bridge is raised. This event is the first to take place in Tower Bridge's chamber, and will feature the premiere of (appropriately named) composer Iain Chambers' work for brass and electronics, 'Bascule Chambers', which is based on a recording of the bridge being lifted. Sessions take place at 11am, 12.30pm, 2pm, 3.30pm, 5pm and 6.30pm. Book in advance on 020 7407 9191.
