Two live recordings at Theatre au Clain, in Poitiers, France and at le Bistrot, in Bayonne, from the free improvising quartet of Christiane Bopp on trombone, Jean-Marc Foussat on synth & voice, Jean-Luc Petit on bass clarinet and sopranino sax, and Makoto Sato on drums, for submersive interchanges blending electronics and acoustics in remarkable ways.

A uniquely voiced dialog between two skilled improvisers -- Christiane Bopp on trombone and Jean-Luc Petit on bass clarinet & soprano sax -- bringing experience and technique to improvisations that push their instruments into extreme territory yielding fantastic and original language while keeps their listeners on the edge of their seats.

A tour-de-force of solo improvisation from French trombonist Christiane Bopp, flawlessly captured by sound engineer Jean Marc Foussat, as Bopp transforms her instrument through technical skill, lyrical ability, and unusual technique, creating virtual duets, furtive expression, and thundering emotion, an absolutely impressive example of modern trombone language.
