Of the many unsigned artists who submitted a song by CD or Mp3, here we have the creme de la creme. Dublin 4-piece Grand Pocket Orchestra trade in a distinctive 'Pavement meets Liza Minnelli' brand of indie, while singer-songwriter Joe Echo, AKA Ciaran Gribbin, has won massive acclaim left, right, centre – and Gary Lightbody.

They join Fight Like Apes, The Parlotones, The Flaws, Kormac (live), Mystery Jets and Republic of Loose DJ sets, and a whole galaxy of Irish and international stars. The festival coincides nicely with the August Bank Holiday (August 2-3).

The 'Your Band At Castlepalooza' competition was set up to help the best of Irish unsigned talent get one more rung up the ladder. Mission accomplished.
