On 4 March, as part of the Barbican’s 40th anniversary celebrations, Barbican’s Associate Ensemble Britten Sinfonia performs Steve Reich’s pulsating City Life (1995), where samples of speech, heartbeats and sounds from urban life are part of the fabric of the piece. The concert also features Brett Dean’s Pastoral Symphony and the world premiere of a new co-commission for the occasion by Dobrinka Tabakova.
