Maine’s Bangor Symphony Orchestra plans to resume live, in-person performances for its 2021-22 season at the Collins Center for the Arts. For the coming season, its 126th, the Bangor Symphony will present five classical concerts, plus special events and three world premieres. Highlights include world premieres by Reinaldo Moya and Jessica Meyer, and Music Director Lucas Richman’s The Warming Sea, presented by the Maine Science Festival; that work’s premiere was delayed from last season due to the pandemic. Concerts will also include works by Beethoven, Britten, Copland, Dvořák, Mendelssohn, and Stravinsky, as well as a joint concert of works by Mozart and Joseph Bologne, Chevalier de Saint-Georges. Guest artists include pianists Joyce Yang and Roberto Plano, Bangor Symphony Principal Bassoon Wren Saunders, Cleveland Orchestra Principal Cello Mark Kosower, and Maine-based mountain dulcimer player Pam Weeks, who will perform in Conni Ellisor’s Blackberry Winter.
