The Muse were fantastic live, so many bands, The Christians in inishowen , only about 500 people at a local bar, sounded great. Simple Minds in Belfast were brilliant. Aha in Dublin , U2 a few times in Dublin, they can put on a show. Simply Red in Dublin were fantastic.
Muse are my favourite band, saw them live loads of times. Best one was the Olympia in Dublin at the tail end of their Absolution tour, can't remember the year.
One of the best gigs I've been at was also in the Olympia, Hall and Oates. Apparently they'd never played in Ireland, absolutely tore the house down
