Two works from composer Frey performed by Montreal's string ensemble Quatuor Bozzini: "String Quartet No. 3", a minimal work of colors, sensations, shadows, durations; and "Unhorbare Zeit" exploring durations without sound, or empty volumes, to achieve lucidity and transparency.

The duo Contour of Stephen Altoff (trumpet) & Lee Forrest Ferguson (percussion) perform Antoine Beuger's "dedekind duos" dedicated to mathematician Julius Wilhelm Richard Dedekind; and Jurg Frey's "22 Sachelchen" or "small things", 22 focused miniature compositions.

Jurg Frey on clarinet and Irene Kurka on soprano vocals perform Wandelweiser composer Antoine Beuger's extended composition "Two"; then the duo of Rhodri Davies on harp and Ko Ishikawa on sho are layered on the first recording, creating a refreshingly new take on the piece.

Antoine Beuger, Burkhard Schlothauer, Chico Mello, Jurg Frey, Kunsu Shim, Michael Pisaro-Liu, and Thomas Stiegler participate in this realization of Christian Wolff's compositions to make sounds or draw sounds out of stones, alone or with other surfaces, acoustically or amplified.

The Ensemble Grizzana (Ryoko Akama, Mira Benjamin, Richard Craig, Emma Richards, Philip Thomas and Seth Woods) performs a series of delicate and beautiful chamber pieces by Swiss composer and clarinetist Jurg Frey, who also performs on clarinet.
