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.
