French electro-house pioneers Justice will be headlining day 1 of the Radio 1 Introducing Stage at Belfast's Tennent's Vital 2007.
They will be joined by Rumble Strips as well as Belfast's very own electro-pop act Oppenheimer and hotly tipped local band Steer Clear.
The festival takes place on Tuesday 21st and Wednesday 22nd August with its strongest line-up yet. Already confirmed to headline the Main Stage are Razorlight, with Manic Street Preachers and The View on Day 1. The second day sees headliners The Killers. Kasabian, Mark Ronson, The Shins and Albert Hammond Junior take to the stage on the second day.
Tickets are on sale now priced at £70 for both days or £38 for either day.
