London's Clapham Common is set to host the the capital's most exciting and diverse dance and electronic music festival of the summer.
The event, which takes place over the August Bank Holiday weekend, will welcome some of the biggest names in the dance arena.
SW4's opening day kicks off the weekend with supreme duo Chase & Status, Carl Cox, Knife Party, and Benny 'Cinema' Benassi. The DJ Magazine arena and The Gallery stages will see Erick Morillo and Paul van Dyk headline.
Skrillex will close the festival on the Sunday, with Public Enemy and Radio 1's Skream & Benga building up to what promises to be a huge finale.
Saturday is now sold-out. A limited number of Sunday tickets are available via Ticketmaster.
