Dance pioneers Orbital are to play their final Irish show at OXEGEN on Saturday 10 July.
Brothers Paul and Phil Hartnoll have been together for 15 years and their festival performance will coincide with the release of their seventh and last LP 'Blue Album'.
Phil Hartnoll said "I think if we're gonna do a last gig we should do a distilled set of all the best stuff we've done. And that's what we're gonna do, play all the stuff that's stuck around for all this time because they are the favourite ones."
Other bands that have also been added to the OXEGEN bill include Goldie Looking Chain making their Irish debut, hotly tipped Irish four-piece Hal and Southampton's Delays.
Tickets priced €59.50 (one day), €110 (two day) and €130 (two day including camping) are on sale now.
