Led by singer-songwriter Dave King, this Irish punk band formed some 20 years in Los Angeles. Last year, it went back to its roots for its most recent album, Anthem, which reunited it with engineer Steve Albini (who worked with Flogging Molly on its first two albums, Swagger and Drunken Lullabies). The current tour brings the group to the Agora for a show with the Bronx and Vandoliers. The concert begins at 7 p.m.
