Multi-genre music is music that doesn't fall into one music category; so, an artist could be both rap and pop and folk for instance. Multi-genre festivals consist of artists of a wide range of genres - the various artists can stick to one genre, but the festival as a whole will have a variety. These festivals are quite popular as there's often an artist and/or genre that ever festival-goer will like.
Multi-Genre festivals include the likes of:
Glastonbury, Reading and Leeds in the UK.
Sziget, Primavera Sound, Way Out West and Rock En Seine in continental Europe.
SXSW, Coachella and Dirtybird Campout in the USA.
Artists as diverse as The Cure, Nina Kraviz, Blood Orange, Bicep and Travis Scott can be seen playing at a number of multi-genre festivals.
