OK, OK, I'm an idiot! I've just listened again to the Second Concerto in the new performance from Kirschnereit on cpo and I have to say that it is utterly gorgeous. I loved it from beginning to end (although I do think that the third movement isn't on the same level as the other two). So I don't know what I was thinking of yesterday and I hang my head in shame. "Even Jove nods, y'know."
