Two major works of evolving acoustic soundscape from Swiss violinist & composer Patricia Bosshard realized by the 27-member Orchestra des Nouvelles Creations, which includes Bosshard, Stephane Rives, Bertrand Denzler, &c.; "Sillon" employs a percussive pulse over 27 independently transforming grooves; "Reflets" a harmonic composition for bowed strings, including three double basses.

French voice artist and composer Yannick GuŽdon living in Brussels composed this extended work, the title translating to "insistence on possibilities", realized with cellist Deborah Walker and violist Cyprien Busolini, Guédon merging extended utterance into long string drones, contrasted with silence, as the piece moves through very specific placement.

This duo arose from the meeting between two violists avid to confront with their instrumental double to create a common sound universe from the same instrument played by two different personalities.
