Other names on the line-up include Example, Ellie Goulding, Basement Jaxx, Madness, Bombay Bicycle Club, Newton Faulkner and Camera Obscura.
"I’m delighted to announce the first names we’re bringing to the party at Loch Ness this summer. We’ve been working hard behind the scenes to bring you an eclectic line up of the highest calibre acts for which RockNess is synonymous," says Festival Director Jim King. "To top it all, we’ve reduced the price of our Weekend Camping tickets by £20 so you can join us at RockNess for less than most other major UK festivals at an amazing value price of £139.
"If you haven’t joined us at RockNess before, I promise you it is the best way to kickstart your summer, a completely electric atmosphere, partying in what is probably the most beautiful festival site in the world. If you have been to RockNess before then as always I’d like to thank you for your continued support in making it the best festival in Scotland.
"We’ve got many more bands and DJ’s still to announce, plus another very special headliner, so stay tuned…!"
The Vaccines are among the first bands on the Rockness line-up
Rockness takes place in Dores, near Inverness, on 7 - 9 June 2013.
