The UK ensemble Apartment House performs two works--Olivier Messiaen's "Quatuor pour la fin du Temps" in 6 movements; and Linda Catlin Smith's "Among the Tarnished Stars"--taking a fresh modern approach to the Messiaen, drawing out its experimental character, and the sense of drama and intricate gradations of sonority in Smith's rich and mysterious work.

When the Zeitkratzer Ensemble was asked to perform a late ensemble work by John Cage, director Reinhold Friedl turned to composer Burkhard Schlothauer, who reworked one of Cage's Number Pieces to create this rich piece using Cage's methods; plus a composition for the dance piece "Bewegte Bauhausbilder"; and an octet commissioned for the Klangzeit-Festival Time Is On My Side.

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.

Four fragile and mostly minimal works by Victoria-based composer Alex Jang, performed by the Apartment House ensemble, with solo pieces by Heather Roche on clarinet + field recordings, one with Cristian Alvear on guitar, an acoustic quintet, and "any three players" designed for any mix of instrumentation, here on melodica, vibraphone & cello.

New ensemble pieces by Jurg Frey and Magnus Granberg played by Ensemble Grizzana, commissioned by Another Timbre with the request that both start from the same two fragments of early music, one by Johannes Ockeghem, the other by William Byrd, each composer producing fascinatingly different pieces that both contain echoes of the source material.

Commissioned by Berlin's Maerzmusik Festival and premiered in 2014, Elliott Sharp's composition & soundscape is named after the Greek waking dream and inspired by John Cage, Sharp using a methodology to filter and process his musical manuscripts via Photoshop, which are interpreted through amplification of acoustic instruments by the Zeitkratzer ensemble.

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.

Leading contemporary music ensemble Apartment House perform a new piece developing out of James Saunders's long-term modular project '#unassigned'; the new piece, "assigned #15" creates a mesmeric, dense, jungle-like soundworld across its 45 minutes duration.
