Over 40,000 people descended on Clapham Common at the weekend to take part in the Bank Holiday festival that is the South West Four weekender.
In its eighth year, the two-day festival which took place on Saturday and Sunday, was virtually sold out and featured some of dance music's big hitters including live headlining slots from drum 'n' bass band Pendulum and veteran dance music kings Underworld.
Crowds also saw Radio 1 DJ's Pete Tong and Annie Mac take to the main stage along with Dubstep outfit Magnetic Man.
A number of other stages also hosted sets from Simian Mobile Disco, Above and Beyond and Judge Jules.
