BST quickly established itself as a world class city festival, and many bonafide legends have graced its stages – The Rolling Stones, Carole King, Stevie Wonder, Bob Dylan, Taylor Swift, Adele – to perform to 55,000 people a night in the heart of the capital.

Proper Productions, who first helped AEG & Loudsound with the pitch document to the Royal Parks to secure the licence itself, and have worked as production directors and artist liaison to bring the entire three-stage site to life every June and July since.
