One of the most highly rated acts of recent times, synth-pop duo All Tvvins, who have already supported Arcade Fire, Pixies and Jungle, make their Festival debut this year.
The duo's collective experience counts for a lot: when you hail from two of Ireland's most acclaimed indie bands of recent years, Adebisi Shank and The Cast of Cheers, you can expect to have a head start.
Róisín Dubh gigs are strictly over 18's.
