With titles taken from different kinds of water nymphs in Greek mythology, composer Mark Iddon's four-part work is a hauntingly beautiful set of compositions of seeming siren calls and rich percussion, realized by an octet configuration of the UK ensemble Apartment House, with two pianists (Philip Thomas and Mark Knoop), three strings, clarinet, flute and percussion.

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.

Inspired by the broadcast performance by The Apartment House ensemble of three works by Morton Feldman, Another Timbre requested that they record the exceptional late work of the minimalist composer, Piano and String Quartet, captured at Henry Wood Hall two months later in a stunning interpretation of this enigmatic work of sensually dissipating motion.

Eight chamber works of interestingly structured and exquisitely restrained character, composed between 2016 and 2021 by UK composer Georgia Rodgers, performed by the Apartment House ensemble in configurations of acoustic duos, trios & quartets, one solo piece for piano & electronics, one solo work for electronics and the title piece in 3 parts by a quintet.

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 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.

Three minimal works for small ensemble incorporating electronics by Australian-born, UK-resident composer Newton Armstrong: 2 performed by the London-based Plus-Minus Ensemble directed by Mark Knoop as an acoustic quartet configuration and one as an electroacoustic quartet; and a solo work for multiple cello layers and resonance performed by Séverine Ballon.

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.

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.

Bryn Harrison's highly acclaimed, labyrinthine composition for violin & piano from 2014, expertly realised by violinist Aisha Orazbayeva and pianist Mark Knoop, for whom this 5-part work of beautiful repetitions reflecting tapestries of sound was written.

"Two Pianos" is one of Morton Feldman's most experimental and radical works, performed here by John Tilbury & Philip Thomas; plus lesser known works including 'Piece for Four Pianos', 'Between Categories', 'False Relationships and the Extended Ending' and 'Two Pieces for Three Pianos'.

Stockhausen's late 60s composition "Mantra" was a return to his intricately systematised approach to musical construction, expanding the possibilities and potentialities of the serial principle to allow for more melodic and embraceable compositions.
