James Conlon continues his exploration of Recovered Voices with a rare performance of the Lyric Symphony by Alexander von Zemlinsky, a onetime star of Vienna’s music scene who fled Nazi Germany and died in obscurity in New York. Opera standouts Melody Moore and Lucas Meachem bring the huge emotions of this ambitious score to life. Conlon, who “conducts like a man with Beethoven encoded into his muscle memory” (The Washington Post), takes a romp through Beethoven’s jovial Second Symphony.
