Swagger. Music writers use this term to describe a variety of bands, but the Dropkick Murphys is one of the few groups that truly deserves it. Vocalist Al Barr and bassist Ken Casey exude so much testosterone when performing their trademark Celtic punk that you can smell the Guinness and Old Spice freely flowing from their pores. This is a man's band, dammit, and if you're going to keep up at the high-impact show, you'd better leave your dainty shoes at home. Let's just try to forget that the band is full of Red Sox fans, OK? Branded: To promote its upcoming album, Signed and Sealed in Blood, the Dropkick Murphys encouraged fans to send in Murphys tattoos. The band plans to use the photos in the packaging for the album, due out next year.
