A white peacock has been sighted in the Vlindertuin. It has been heard reciting in French, denouncing the state of society with punk fury, and singing what, according to some, is the most beautiful song ever heard in the Vlindertuin. It has been rumoured that this animal is attracted to musical instruments. So Arthur, your host for this event, decided to organise a jam. Open to musicians of all levels, the only condition is no existing songs, covers and the like. Improvised music only. Make those asses and feathers shake!
