More than 30,000 revellers will descend on Co Laois today for the Electric Picnic music festival.
Bjork, The Stooges, Chemical Brothers, Spiritualized and Primal Scream are among the top acts that will take to the stage tonight, tomorrow and Sunday. The Beastie Boys will do their first Irish show in over a decade.
The festival, now in its forth year, has grown from being a one-day music-fest to a three-day party encompassing music, the arts and poetry.
However, the Picnic has kept its trademark intimacy intact by realising just 32,500 tickets - all snapped up before the line-up was announced.
The line-up also includes ex-Pulp frontman Jarvis Cocker, a hark back to 1980s punk-pop with The Jesus And Mary Chain, cutting edge dance-rock from LCD Soundsystem, and the first-ever Irish show by the Damon Albarn-led The Good, The Bad and The Queen.
A warning has been issued to revellers driving to the festival - especially those driving home the morning after drinking. Gardaí have said they will be out in force in the area to ensure drink drivers are caught.
