Liam's Brother--If you're into Irish music (Knowing you, it's sort of like starting "If the sun will rise in the East tomorrow...") there's a wonderful session at Paddy Mac's in downtown Silver Spring on Sunday afternoons from 4 to 7 p.m. It's an Irish pub on the second floor at the corner of Georgia Avenue and Thayer Street, about 4 blocks from the Metro station.
