The last few names have been added to complete the Tennent's Vital line up for 2007.
The Holloways will be headlining Day 2 of the Radio 1 Stage, and will be joined by Belfast's Alloy Mental and I Was A Cub Scout.
The second day's local acts include the band recently featured in our look at up and coming music in Ulster Kharma 45 and Black Alley Screens.
Now in its 6th year, Tennent's Vital returns to Belfast 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 has headliners The Killers, with Kasabian, Mark Ronson, The Shins and Albert Hammond Junior.
