As Arthur’s Day approaches on September 24th, more acts have been added to the already extensive bill of musicians gathering in Dublin to celebrate the 250th birthday of Guinness.

Hip-hop innovator Roots Manuva is joined by Scottish singer Paolo Nutini, indiepop favourites The Magic Numbers, LA power- poppers OK Go and noise- rock duo White Belt Yellow Tag. Irish acts include David Kitt, Oppenheimer, Fionn Regan, The High Kings, General Fiasco, Jerry Fish and the Mudbug Club, The Coronas and The Infomatics.

Ronan Keating and Cat Deeley will host the main event in Dublin, at the invite- only Hopstore 13 venue at St. James’s Gate. The four studio venues (Whelan’s, Tripod, the Academy and Vicar St) will be hosted by the BBC’s Colin Murray, Phantom FM’s Michelle Doherty and TV presenter Michelle de Swarte. At the same time, Sean Paul will play in Lagos, Nigeria, and Black Eyed Peas will headline a show in Kuala Lumpur, Malaysia.
