The Metropolitan Opera continues Saturday on Classical 90.5 with Alban Berg’s Wozzeck. Wozzeck, which premiered in Berlin in 1925, is based on a play by Georg Buechner written nearly a century earlier. It tells in 15 brief scenes the tale of a common soldier driven to madness, murder and death by the merciless forces of society. James Levine interprets Berg’s masterpiece. Alan Held sings the title role and Waltraud Meier brings her interpretation of Marie to the Met for the first time.
