Rock Werchter can today already a headliner for the next edition to advertise. Mumford & Sons arrive on Saturday 29 June at the Festivalpark. The beautiful single ‘Guiding Light’, the precursor of the new album ‘Delta’, on 16 november, opens, and has won many hearts. Mumford & Sons are overachievers. They write the most beautiful songs. Their performances are never less than magnificent. It is a reunion where hard to change will be.
