The Vaccines, Ellie Goulding and Palma Violets have joined the lineups of this year's Ibiza Rocks and Mallorca Rocks festivals, bolstering a list of performers that already included Jake Bugg, Foals and Example.

"We're really looking forward to getting out there," the Vaccines' Freddie Cowan said of the gatherings, according to NME. "Last time we went was two years ago and it was in the middle of such a busy summer so this time we're hoping to spend a bit more time on the islands and maybe enjoy the Ibiza Rocks House at Pikes. They filmed 'Club Tropicana' there!"

Ibiza Rocks is an annual summer-long festival that takes place on the Mediterranean island of Ibiza, off the coast of Spain. It goes down one night a week over the course of several months, and this year's fest launches June 5 and runs through Sept. 19. Ibiza's sister event, Mallorca Rocks, takes place on nearby Mallorca island and also features weekly performances. The 2013 go-round spans June 4 through Sept. 18.
