As a place of sharing, encounters and experimentation around music, Jazz au Vert gathers passionate and curious amateur musicians, as well as young professionals. At the end of the week-long masterclass, participants get to proudly present the fruit of their labor at the Grand-Théâtre de la Marlagne. Throughout the evening, free concerts open to all start at 6:30pm and run well into the night. The well-established jam session follows and wraps a magical week in Wépion.
