Sounding joy

The West Newbury-based Merrimack Valley Concert Band will present its annual Christmas concert this Friday at 7 p.m. in the Pentucket Regional Middle School auditorium, 20 Main St., West Newbury.

Formerly known as the West Newbury Veteran Fireman’s Association Concert Band, the group harkens back to the days when rural communities fought fires with volunteers, bucket brigades and horse-drawn or hand-pumped fire apparatus.

Admission is free. Intermission will feature a bake sale to raise money for the band’s yearly scholarship to a Pentucket student.
