“The Longwood Symphony Orchestra is made up of members of Boston’s health care community, including nurses, doctors, researchers, and medical students,” writes Jeremy Eichler in Monday’s (12/16) Boston Globe. “Founded in 1982, it’s earned a distinguished place among the area’s rich network of community orchestras thanks to its unusual makeup, its adventurous programming, and its engaged social mission…. Two-thirds of Saturday’s program in Jordan Hall consisted of works by living composers…. The night opened with John Harbison’s ‘Remembering Gatsby’ (Foxtrot for Orchestra). … Next up was Joan Tower’s ‘Duets,’ an intricate concerto for orchestra built out of soloistic duos played in pairs by various members of the orchestra…. On Saturday, both of these challenging contemporary pieces, while seemingly pressing the all-volunteer orchestra to the edge of its capacity, also brought out its best, as music director Ronald Feldman, at key moments, drew out expressively rich and deeply committed playing.” Also on the program was Brahms’s Double Concerto, featuring violinist Ayano Ninomiya, a Naumburg Competition winner and New England Conservatory faculty member, and Boston Symphony Orchestra Principal Cello Blaise Déjardin.”
