Sigur Rós are the first band to be announced for this summer's gig series at the Royal Hospital in Kilmainham.
The Icelandic band - always firm favourites with Irish crowds - will play the Dublin venue on June 26th, with support from James Vincent McMorrow.
They are believed to be working on the follow-up to 2013's 'Kveikur' at the moment, while McMorrow's last release was 2014's 'Post Tropical'.
Tickets are €49.50 and on sale from usual outlets next Friday, February 5th at 9am from usual outlets.
