Christiaan will be present in Samois and surroundings during the yearly festival held at the Fontainebleau Castle.
He is not on the festival program to perform on stage, but you can sure find him jamming anywhere else! Go find him at the festival site or at the Samoreau campsite for a chat or a jam. He might be too occupied for lessons, but you can always try. Best chances to catch him? Try somewhere between 2pm and 5am!
