The French saxophonist Sébastien Branche, based in Leipzig, focuses on sound as a material and typically performs at the intersection of drone, noise, and bruitism, incorporating long tones, extended techniques, or objects into his improvisations. Interested in collective and non-hierarchical experiments, he has been a member of several collectives and is currently part of IMO (50+ musicians) and co-founder of Ensemble Modéle Réduit (partially determined music). Besides playing in various bands, he performs solo as Lignes de crête, an electroacoustic solo where the saxophone controls and processes electronic sounds, as well as in Lignes de niveaux, where the saxophone is deconstructed and spatialized with ambisonics. Sébastien is also an active figure in Leipzig’s free music scene, organizing jam sessions and concerts including the LiLe series and the ZiXP Festival, and hosts the show Carte Branche on Sphere Radio.
