Last night, the first details were confirmed about this year's Orange RockCorps events. 

Jessie J, Primal Scream and Eliza Doolittle will perform at London's Wembley Arena on July 12 as part of the initiative, and fans will be able to get their hands on tickets by giving up 4 hours of their time to volunteer for different charites. 

One of the event's organisers, Andy Pearcey, explained that the line up was designed to be universally appealing:

"We've got a phenomenal line-up at the Wembley gig, it will appeal to a variety of musical tastes."
