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".

Recorded in the mid-90s, Livebatts! was a project of John White (Cornelius Cardew, Scratch Orchestra) developed to exploit "toy" keyboards of the 80s--cheap battery-driven instruments that hold tremendous potential for "serious" music-making--used here in a playful quartet with vocalist MJ Coldiron, Andrea Rocca (guitar & samples) and Nancy Ruffer (electrified flute).

Splitting the album between two ensembles, UK composer Eden Lonsdale's beautifully languid compositions are performed first by Apartment House, and then by the young Rothko Collective, the four pieces showing Lonsdale's development of writing for harmony, timbre and resonance into works focused on the passing of time and the integration of prominent melodic elements.

Six sound-oriented compositions for acoustic ensemble performed by the UK ensemble Apartment House, beautifully reflective and rich works, the first six pieces being text scores for open instrumentation, along with Peace/Tree, a seven movement work for violin, cello and piano that specifies pitches while leaving room for interpretation and improvisation.

Eight sophisticated chamber pieces composed by Linda Catlin Smith and realized by the Canadian Apartment House ensemble, including a solo piano performed by Philip Thomas, a piano duo with Thomas and Mark Knoop, and works for percussion & cello, 2 quintet pieces for strings, percussion and winds, and two 7-piece conducted works with two percussionists, strings and brass.

Three works from Canadian composer Chiyoko Szlavnics, two electroacoustic compositions incorporating sinewaves, one with a saxophone quartet and the other with two accordions, two flutes and two percussionists; and a string trio of long sustained tones and slow glissandi.
