How's this for art-rock? The National will bridge the gap between performance art and music when they play their song 'Sorry' for six hours straight as part of an art installation called 'A Lot of Sorrow' by Ragnar Kjartansson in MOMA PS1 in New York on May 5th.

A press release from the gallery said that "by stretching a single pop song into a day-long tour de force the artist continues his explorations into the potential of repetitive performance to produce sculptural presence within sound.

"As in all of Kjartansson's performances, the idea behind A Lot of Sorrow is devoid of irony, yet full of humour and emotion. It is another quest to find the comic in the tragic and vice versa."

The National will play Cork's Live at the Marquee towards the end of June and again in Dublin's O2 on November 10th.
