Did anybody attend this? I watched it on BBC2 and had a pretty good time, at least in the first half. I was pretty surprised at the excellent job that the National Youth Orchestra made of Ameriques: it had obviously been rehearsed pretty thoroughly and the orchestra sounded (and looked) secure. Yes, there were complaints, but they were minor - (e.g., unconvincing trombone group decrescendos, a couple of less than incisive Eb clarinet solos, a siren that sounded not in the least bit scary). Boris Berezovsky was impressive in the Rachmaninov - in fact he seemed the ideal pianist for the work.
The bad news was the Copland 3rd Symphony, which was new to me. It seemed a really flabby work, frankly, and it was presented with considerably less gusto and precision than the preceding pieces. I'm usually quite sympathetic to Copland, but not on this occasion: or perhaps it was just the performance?
I also watched on the box, and agree with you autoharp, but you had best stay away from TOP. Not only was the Varèse rubbish (the work, that is) but Berezovsky, in playing marginally faster than the composer did (and only marginally), ruined the piano concerto, or so I am led to believe.
