The UK avant ensemble Apartment House performs three of John Cage's later works: Two (1987), a number piece using randomly-determined time brackets specifying pitch & dynamic; Hymnkus for up to 14 instrumental parts each of 17 elements blending the concepts of a hymn and a haiku; and Thoreau Drawings, the score twenty unnumbered pages on which Cage drew shapes onto a grid of six systems, each divided into 5+7+5 parts, following the form of a haiku.

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".

Three chamber works in single and multiple movements by minimalist composer Jurg Frey, exploring time & duration, form & shape and a balance of material, performed by a core quartet from the UK ensemble Apartment House, orchestrated for clarinet and bass clarinet, violin and cello, the final work adding piano, viola and percussion in a septet reworking of a 2014 composition.
