A 4-disc box-set with a 44-page booklet of extensive notes, presenting John Cage's Number Pieces which he wrote in the last five years of his life, adapted for mid-size ensembles and performed by the London-based ensemble Apartment House, compositions 'Five' to 'Fourteen' along with alternative versions of three of the pieces; significant and essential.

Five fascinating works by the Belgian composer Maya Verlaak, realized by Apartment House and soloists Sarah Saviet & Mark Knoop, experimental compositions including a work of personal reflection based on "Alouette"; a conceptual game piece; a composition layering pre-recorded segments of "Greensleaves"; and two interactive acoustic & computer pieces.

A live recording of Julius Eastman's 1974 work "Femenine" performed by Apartment House led by cellist Anton Lukoszevieze, with Simon Limbrick on vibraphone, Kerry Yong on piano, Mark Knoop on keyboard, Mira Benjamin on violin, and Gavin Morrison and Emma Williams on flute, an ecstatic and intricate work using a repeating figure contrasted with both asynchronous and complementing backgrounds.

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.

Ten pieces dating from 1995 to 2015 from Canadian composer Linda Catlin Smith, performed by Quatuor Bozzini and Apartment House, the first in Another Timbre's Canadian Composer series, a 2-CD release focusing on Smith's "equal and simultaneous drive toward abstraction and lyricism" in slowly developing, lush and sophisticated compositions.

Canadian composer Linda Catlin Smith's extended composition for violin and percussion in 15 parts, performed by percussionist Simon Limbrick and violinist Mira Benjamin, a unique orchestration that reveals a journey of steady pace, tension and beauty.
