Black 47 + Girsa

Guinness at the ready—it's the Brooklyn Irish Music Festival. Local outfit Black 47 (named after the worst year of the Irish Potato Famine in 1847, fact fans) and all-gal Irish-American crew Girsa headline this weekend's bill. Other acts include Seanchai & the Unity Squad, The Fighting 86's, Three Pints Shy, Boston’s Erin Og, Strayaway Saints, MacTalla Mor and the Snakes.
