Back by popular demand: This youthful Chicago-based quartet was described by Dirty Linen in 2009 as playing with “a precision and intensity that is rarely heard on this side of the Atlantic” and in a style “largely forgotten in today’s overly polished Irish music world.” They have performed and taught at regional Celtic festivals from Milwaukee to the Catskills and at Old Songs and the National Folk Festival, among others. They were the Irish Music Association’s “Top Traditional Group” of 2009. Bua is Brian Ó hAirt (lead vocals, sean-nós dance, concertina), Sean Gavin (flute, uilleann pipes, whistle), Devin Shepherd (fiddle), and Brian Miller (guitar and bouzouki). At the Lyceum of Alexandria, 201 S. Washington Street (on the free trolley line from King Street Metro station, running every 15 minutes). $20, members $10. (Note corrected date: Sept. 21.)
