Dans Les Arbres has been played on NTS shows including Don't Trip w/ Margarita, with Luminescent first played on 22 April 2017.

Guitarist Ivar Grydeland and percussionist Ingar Zach, prime movers and catalysts for free improvised music in Norway, got in touch with Christian Wallumrød after hearing his “Sofienberg Variations” on ECM and they have since worked together in diverse combinations including, since 2004, ‘Dans les arbres’ a project completed by French clarinettist Xavier Charles. Their radical all-acoustic improvisation explores sonorities and textures that frequently sound electronic, and also often sounds ‘composed’ – with echoes of Cage and the New York School.
