Should the music critic look at a score or listen to a recording before attending a performance of a new work? Tim Mangan says yes: “Virtually any piece of serious classical music that a listener is not familiar with is ‘just an overwhelming event’ the first time he hears it. There’s so much going on that our ears can’t comprehend it in one gulp. And who knows whether, that first time we hear a piece, be it Brahms’ Third Symphony or Adams’ ‘Transmigration,’ it’s a good performance or bad?”
