Five varied and fascinating percussion duos under the title "Rhythm Mapping - Approximating Velocity" from French composer Karl Naegelen and performed by the duo of Sylvain Darrifourcq and Toma Gouband, both using traditional drums and percussion along with objects and vegetal lithophones (a collection of plants and stones); an innovative, upbeat and compelling album.

Transcendental and exceptional improvisation in the 2nd release from the Fenetre Ovale project, with composer Karl Naegelen and improvisers Eve Risser (piano) and Joris Ruhl (clarinet), expanded with the arrival of percussionist Toma Gouband and violinist Amaryllis Billet.
