Launching the festival, director Declan McCarthy said "We're delighted to be able to bring Cork X Southwest back for a fourth year and we thank MURPHY’S for their continued support. We’ve managed to add an international flavour to the line up for 2010 and are honoured to be welcoming artists of the calibre of Martha Wainwright and Bonnie Prince Billy to Skibbereen. Our line-up celebrates the very best music that Cork and Ireland has to offer, with younger artists such as Mick Flannery and O Emperor performing alongside veterans such as Hot House Flowers and Luka Bloom. Here at Cork X Southwest, we have one, simple goal and that’s to bring the best musicians and keenest music lovers together for a day and night of damn good music sessions, a creamy pint or two and a belly-full of real West Cork food."
