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.

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.

Known mostly as a masterful improviser, this 2015 live performance of her 2009 work for a tenet crosses compositional and improvisation boundaries, reflecting on her 40 year career while bringing out new subtleties from its original release, here with a superb set of performers.
