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.

The UK ensemble Apartment House commissioned this work from composer & experimenter Jim O'Rourke based on their performance of other O'Rourke works, here interpreting a new graphic score designed like a sonic mobile, creating a minimal yet episodic piece of flexible interpretation as the performers whistle, hum and quietly sing in combination with bowed harmonics.

The 4th album on Another Timbre from a series of pieces by composer Antoine Beuger, each acknowledging a cultural or intellectual figure, here titled for philosopher, musicologist, educator and one-time member of the French Resistance, Vladimir Jankélévitch, represented by Beuger in a large dramatic work performed by the Apartment House sextet.

The UK Apartment House ensemble perform four chamber works or lyrical ballads of slowly meandering melody, referenced as slow dances, by Toronto composer Martin Arnold: "Lutra" for solo cello & humming; "Stain Ballad" for a sextet of strings, piano, reed organ & percussion; "Trousers" for violin & cello; and "Slip" for cello, violin, bass clarinet & piano.

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.

Apartment House play five chamber pieces by American outsider composer Luiz Henrique Yudo, most of whose works are transcriptions into sound of existing artworks, including three short pieces with dedication, the 5 part and quirky "Five Palindromes" and followed by an extraordinary long work based on the patterns in colour artworks, "The Donald Judd Harmonies".

Morton Feldman's final composition, originally premiered in 1987, here performed by pianist Mark Knoop, violinist Aisha Orazbayeva, violist Bridget Carey, and cellist Anton Lukoszevieze, recording a year after their successful performance at London's Cafe Oto, maintaining focus and concentration on this large, unhurried work of micro-variations.

Six musicians from the UK Fluxus group Apartment House, including Philip Thomas (piano), Bridget Carey (voila), Anton Lukoszevieze, Simon Limbrick (percussion), present several realizations of composer Joseph Kurdirka's pieces, including text scores and fully-notated works.

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.
