With titles taken from different kinds of water nymphs in Greek mythology, composer Mark Iddon's four-part work is a hauntingly beautiful set of compositions of seeming siren calls and rich percussion, realized by an octet configuration of the UK ensemble Apartment House, with two pianists (Philip Thomas and Mark Knoop), three strings, clarinet, flute and percussion.

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.

Composer Martin Iddon in a work of new conceptual modes of music making, with a ritualistic approach building strange sounds and stange actions in dense layers and intense timbres that demand a unique physicality from the player.
