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.

Canadian composer Martin Arnold is based in Toronto, writing melodic works that contain a meandering, psychedelic quality, as heard in these three compositions performed by Philip Thomas on piano and Mira Benjamin on violin, the first two pieces solos from each respectively, and the last a duo with both musicians.

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.

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.

Four large and distinctive works by composer Christopher Fox performed by pianist Philip Thomas, who also writes the liner notes about the works, revealing and explaining the compositional elements, piano preparations, and physical requirements placed on the performer.

Commissioned by BBC Radio 3 with an ensemble including Tim Berne, Joe Morris, Rhodri Davies, Jim Denley, Alex Ward & Steve Beresford, this amazing work is organized in traditional movements using a very modern and free language.
