Radio 1 will hold the BBC’s biggest ever free ticketed live music event, on Hackney Marshes on 23-24 June 2012, as part of the London 2012 Festival.

Leona and Plan B will be joined by over 80 international and UK artists, bands and DJs making it the biggest multi-artist line up ever for Radio 1.

The six stages will include the Radio 1 Main Stage, the 1Xtra Arena, the In New Music We Trust Stage and the BBC Introducing Stage.

The massive event will replace Radio 1’s annual Big Weekend festival in 2012 and, as with the Big Weekend, the majority of tickets will go to people living in Hackney and the surrounding boroughs.
