BSO launches listeners into spring By Marcia Gronewold Sly Special to The Ellsworth American BANGOR — The Bangor Symphony Orchestra’s second Masterworks concert of the 2021 season began Friday evening with Arvo Pärt’s “Cantus in Memoriam Benjamin Britten,” performed by a small string orchestra and one percussionist under the baton of Music Director and Conductor Lucas Richman. The piece began with three beats of silence, interrupted by the tolling of a bell on a single note. Then the violins began at the top of their register, playing a descending minor scale. One by one, the orchestra’s other sections joined the downward spiral, creating layers of sound. The bell sounded intermittently throughout the eight-minute piece, which ended as it began, in silence.
