An annual feast of experimentation, creativity and skill at Laus Polyphoniae: the summer school organised by Musica, Cappella Pratensis and AMUZ. With facsimiles of centuries-old sources as their guide, a group of adventurers have spent a week delving into music that touched the scaffolding of the cathedral builders. Will the singers succeed again this year in cracking the codes in the score? This showcase is the moment suprême when the magnificent result of their dedication, teamwork and boundless enthusiasm is revealed.
