Four evenings of jazz in the courtyard of Château de Sceaux with a lineup that tilts toward emerging voices: Lea Maria Fries' experimental indie-jazz, Lakecia Benjamin's alto swagger, and the piano-bass pairing of Roberto Fonseca and Vincent Segal. The festival keeps a family pulse too, with free afternoon sets and Antonin Leymarie's immersive Morphing trio where kids can move among the musicians.
