Influenced by New York School composers, Fluxus, Oliveros Sonic Meditations, and Wandelweiser, Boston-based composer Nomi Epstein's fascinating scores take unique and experimental approaches to composition, heard here in three chamber works, two recorded by London's Apartment House, and a live recording from a 2019 concert in Berlin, "sounds for Berlin".

Two hauntingly beautiful works in microtonal composer and violist Catherine Lamb's "Prisma Interius" series, the first a duo with violinist Johnny Change and Xavier Lopez on the "secondary rainbow synthesizer", which channels the sound outside of the performance space as a generator of ambient sound; then a sextet of strings and winds with two secondary rainbow synthesizers.
