South West Four is a London dance music festival held on Clapham Common every August bank holiday weekend.

Known as simply SW4 to locals, the festival teams up with a host of promoters and brands to showcase the biggest names in electronic music across multiple stages. 

This year's lineup will see the likes of Marshmello, Chase & Status, Dizzee Rascal and Armin van Buuren head up a bill that spans from house, techno and EDM, through to drum and bass, garage and jungle.

And once the main festival finishes, festival-goers will find a steady stream of others filtering out into the London night, keen to carry on the party till sunrise.
