Four clarinet-based works in trio, duo and solo from UK composer and musicologist Martin Iddon, performed by Heather Roche on bass and contrabass clarinets, Juliet Fraser on voice for "Muses", Anton Lukoszevieze on cello and James Opstad on double bass; music with intricate, interweaving lines, the title piece a mesmerising work for multi-tracked clarinets and field recordings.
