Rapper will headline the event's opening night (June 23)

Jay-Z will headline BBC Radio 1’s Hackney Weekend event: a huge outdoor festival set to take place this summer to celebrate the 2012 Olympic Games.

The event will take place on London’s Hackney Marshes on June 23–24 and will hold up to 100,000 people. The ’99 Problems’ rapper will headline the event’s opening day (June 23), with a second headliner set to be confirmed in the coming weeks.

The majority of the tickets for the event, which will all be free, will be given to residents of Hackney and the surrounding London boroughs.

Among the other acts confirmed to play the event are Florence And The Machine, Plan B, Lana Del Rey and Jack White.
