The Lovebox festival, running since 2002, was founded by dance duo Groove Armada.
The event has now extended to Sunday, with Grace Jones and Hot Chip amongst the acts set to perform at what organisers say will be "groundbreaking, no-holds-barred, non-stop polysexual party, pulling together elements of the very best gay clubs, fiercest underground parties, cutting edge fashion, hottest emergent artists and, of course, outrageous, unmissable live acts to create a hedonistic all-dayer like no other."
Tickets are available now with one-day tickets available for £45, two day tickets for £80 and three day tickets for £99 (each includes an additional booking fee).
