BSO delivers delightful still available online Reviewed by Marcia Gronewold Sly Special to The Ellsworth American ORONO — To presented last Friday’s Masterworks IV concert, “Mozart & Schubert,” Bangor Symphony Orchestra Music Director and Conductor Lucas Richman made the most of a reduced orchestra and fit together three works that share similar instrumentation. The online concert also included the little-known composer, Marianna Martines’s Sinfonia in C Major. In his pre-concert talk, Maestro Richman expressed his delight at discovering the piece. Featuring Martines, he noted, advances the symphony’s goal of programming works by composers, including women, who are under-represented in Western classical music. Scored for strings, flute, oboes, French horns, and harpsichord, the Austrian composer’s Sinfonia is a charming piece in three movements.
