Werk: Four quartets for male voice, D.983 (Op.17)

As they strode onto Cadogan Hall's stage, New York Polyphony were already living up to their image, one hand-tailored to New York's intellectual, social-media savvy hipsters. It wasn't long before they proved that style went hand-in-hand with substance, in a programme outstanding in vocalism and musicality.
