Norman Lebrecht is impressed with the Metropolitan Opera’s choice of Peter Gelb as its new top man. Impressed in the wrong way. “When I tell you that the new man has done more over the past decade to remove classical music and opera from public consumption, you will understand that the simmering scandal at the Met has the gelignite to blow a hole in opera far larger than all the petty mishaps of English, Scottish and French national operas put together.”
