One of Ireland's biggest exports is music. To name a few, there's U2; Thin Lizzy; Westlife; Boyzone; The Pogues; The Corr's....
If you want to find out more about music from Ireland, and in particular the Dublin scene and influence, I'd recommend the
Dublin Rock 'n' Roll Bus TourIt lasts 75 minutes, and you are driven round Dublin in an American style tour bus, complete with leather seats and blacked out windows. The guys who do the tours really know their stuff as well.
If you'd rather walk and go to the pub all at the same time, there's also a
Rock 'n' Roll Musical Pub Crawl which takes 2 and a half hours
