What to Do Tonight: Flogging Molly

There are very few bands that are as rousing in concert as Flogging Molly. While the Pogues may have invented Celtic-punk, the Los Angeles septet has perfected a sound that reaches its apotheosis in its rafter-shaking performances. Irish frontman Dave King draws upon his heritage and squalid, difficult Dublin upbringing in his anthems of hope and resilience — whether singing paeans to his long-dead dad (“If Ever I Leave This World Alive”) or the irrepressible human spirit (“Life in a Tenement Square”). Traditional Irish folk instrumentation — fiddle, mandolin, tin whistle and accordion — provides a timeless foundation for the rebellious race of punk rhythms and electric guitars. The combination suggests an indefatigable jig that sweeps you up in its energy. Not one of Molly’s four albums can match the vibrancy of their shows, a big reason why they’re supporting Live at the Greek Theater, a three-disc set that includes more than 90 minutes of music plus a DVD. Opening act Frank Turner is nearly as vital. His canny, hard-strummed folk-punk recalls Billy Bragg fueled by keen wit rather than agitprop. He rages against incipient adulthood if it means “being bored and unfulfilled” and longs for the freedom of “The Road.” Formerly of U.K. punks Millions Dead, Turner has released two albums characterized by sure-footed melodies and infectious choruses. The Architects start things off at 8 p.m. at House of Blues (308 Euclid Ave., 216.523.2583, houseofblues.com). Tickets: $29.50-$40. — Chris Parker
