Time to get your kilt dry-cleaned and polish your boots: Flogging Molly is returning to town. LA's most famous seven-piece Irish punk band has specialized in the finest tavern sing-alongs this side of the Atlantic Ocean for more than a decade — which means it's perfected the art of striking while the iron is hot. The band always seems to come to St. Louis near St. Patrick's Day, and its overall activity seems to have increased since Boston's Dropkick Murphys appeared all over 2006's Oscar-winning film The Departed. If there's an East Coast/West Coast Celtic punk war brewing, though, Flogging Molly actually has the upper hand: Its album Float debuted at No. 4 on Billboard last March, a crowning achievement not only for the band but for its genre as well.
