The famed Celtic punk rockers will be at Pier 54 tonight from 6 to 9 pm. Known for their superb live shows, as all 7 of them show up to play, Flogging Molly sounds like old Irish ballads, with tin whistle and mandolin to boot, except played at triple speed and angry as hell instead of melancholy. They’re definitely something you’re into or you’re not, but if you are, you can check out their music and their antics tonight for no charge.
