The American metal heavyweights are set to play at the iconic venue as part of their Worldwired Tour.

The hefty task of opening proceedings will go to Dublin rockers Fangclub.

Though first on the bill, they’re far from inexperienced having already played with the likes of The Pixies and Smashing Pumpkins as well as gearing up to release their second album.
