Antoine Beuger's piece merges compositional and improvised approaches, drawing on the text "the memories of RN", as he performs on flute, voice and objects with the electroacoustic improvising ensemble Colectivo maDam, merging long instrumental phrases with words, syllables or letters, using space and detachment to create numerous possibilities to resonate.

A beautiful rendering of French composer Eric Satie's 1918 masterwork "Socrate", originally for four sopranos and chamber orchestra, here stripped to its essence as a duo with Olalla Aleman on soprano and Guy Vandromme on piano, maintaining Satie's characterist reserve and refinement in the 3 parts: "portrait of socrates"; "banks of the ilissus"; and "death of socrates".

Two clarinetists--John McCowen, also the composer, and Madison Greenstone, both on clarinet & bass clarinet--taking the title from Boethius' (427-524 AD) printed work on ancient Greek music: "De institutione musica", as they generate long-form drones using the harmonic interactions and interference patterns of similar tones, overtones, and difference tones; impressively intense.

London-based composer Emmanuelle Waeckerle in a project of spoken word, flute and melodica with contributors including Antoine Beuger, using minimal and multiple narrations in texts that blend erotic literature, conceptual writing and verbal scores, presented as 2 Scores for voice(s) and instrument(s) based upon Pauline Reage's "Story of O".
