Veering from extreme vocal pyrotechnics to delicate sound-traceries, EXAUDI’s annual showcase features an eclectic line-up of new work, including Leo Chadburn’s homage to the art of holiday postcard-writing, Jürg Frey’s luminous setting of an ancient Chinese proverb, and a major new work from Andrew Hamilton marking the centenary of the Easter Rising. Newton Armstrong’s subtle merging of live and recorded voices, Claudia Molitor’s absurdist vocalising and Naomi Pinnock’s exploration of the borders of sense and nonsense complete the programme.
