Forget Aerosmith or the J. Geils Band — the ultimate New England band is the Dropkick Murphys. Not only do they wear their Boston pride on their sleeves, but the Beantown-based Irish-American punk band has also provided the soundtrack to the victorious recent seasons of the Red Sox, the Patriots and the Celtics. In addition to such instant classics as “Tessie” and “I’m Shipping Up to Boston,” both of which have gotten serious airplay on local radio station WKIT 100.3, the band writes songs about unions, working-class Boston folks and the occasional love ballad. Sure, there are bagpipes, fiddles and tin whistles throughout their six albums, but make no mistake: the Dropkick Murphys are as American as they come. The band plays tonight, Thursday, at 7:30 at the Field House on the University of Maine campus, and you can expect that they’ll play their usual high-energy, rowdy set, full of shout-along choruses and fist-pumping riffs. Tickets are $10-$15 for students and $20 for the general public, and are available at www.umainetix.com, or by calling 581-1701.
