KASK & Conservatorium gathers 50 percussionists – from its own ranks and from other major conservatories in Europe – around a simple but ingenious concept by Julian Sartorius. They will join forces to activate the medieval centre of Gent with rolling drum patterns and analogue sound filtering. All conservatories will prepare the concept beforehand in their respective classes, and the students of the advanced master in contemporary music of KASK & Conservatorium will be responsible for the preparation of the filtering objects and the overall dramaturgy. They will be joined together in partial rehearsals at first and will rehearsal in full numbers two days before the concert.
