Artist Paul Elliman continues his interaction with city sounds and the non-verbal messages of emergency vehicle sirens at point 7, close to the major thoroughfares of the Edgware Road, a key transport route through Northwest London. Elliman has been working with soprano Charmian Bedford and DreamArts youth group (based at The Cockpit Theatre on Church Street) to form a kind of emergency choir that can sing back to the sirens. He will lead a public ‘siren-walk’ event around the area, responding to the range of siren tones as well as observing, testing and discussing the impact of these sounds on urban life.
