BOOTHBAY HARBOR — What does it take for a bluegrass band to remain popular for more than four decades? For the Seldom Scene, it’s taken not only talented musicians, a signature sound, and a solid repertoire, but also a sheer sense of fun. On Aug. 4, the Grammy-nomianted Seldom Scene will be on the historic Opera House stage at 7:30 p.m.

Seldom Scene has become one of the single greatest contributors to the progression of bluegrass while setting a new standard and attracting new audiences to the genre. Their legendary weekly DC-area residencies included bluegrass versions of country music, rock, and even classical pop.

Despite a long touring history, the Friday show marks the band’s first appearance at the Opera House. They often tour south of the Mason Dixon line, and the Opera House concert is their only New England appearance this summer.

Tickets are $27 in advance or $32 on the day of the show. There is a $2 per ticket handling fee. The Opera House box office is open 8 a.m. to 2 p.m. Tuesday through Friday at 86 Townsend Ave., or call 633-5159. Tickets and information are also available
