Guinness, Hot Press and RTÉ 2fm are offering Irish acts the chance to play the main stage on Arthur's Day in Dublin (September 22).
To be in with the chance of joining the star-studded line-up, bands and solo acts over 18 years of age from the Republic of Ireland and Northern Ireland have until August 12 to submit their entry via: http://2fm.rte.ie/pages/Playontheday.
The judges will then decide on a shortlist of artists in four regions to go forward to the second round.
At this point, a track from each of the acts will be made available on the Arthur's Day website, where the public can vote for their favourite.
Following the public vote, the top four acts in each region will go forward to the live regional finals, scheduled for September 7 and 8. Following this, four regional winners will be announced.
