Last night was the latest installment in my season ticket with the National SO. This was the first program of the year in which I had not heard any of the music before. On the program was Diamond, Romeo and Juliet suite; Mozart, Piano Concerto 24; and Elgar, Symphony No. 2. Don't ask me how I've managed to miss the latter two; I'm at a loss to explain it. The NSO was guest-conducted by David Zinman. For the umpteenth consecutive time, a modern work has failed to be as intimidating as I thought it would be. Diamond's R&J was wonderful: tonal, accessible with a slight edge, interesting orchestration. If a concert was being given that comprised the three main contemporary works I've heard this year -- Diamond's R&J, Glass's Symphony No. 7, and the Corigliano Piano Concerto -- I would not hesitate to recommend it...or to see these works performed again. Peter Serkin played Mozart's PC 24 in place of Radu Lupu, who had to cancel due to surgery. I was jittery about this: A couple of years ago on the Mahler-List, Serkin got hammered for apparently murdering a Brahms concerto in New York. Last night he was flawless, in great tone, and in perfect ensemble with the NSO. Not being familiar with the piece, I still thought Zinman took it a little slower than others might; on the other hand, any faster and nobody could keep those glissandos in tempo. It was a really good rendition of what the program notes called the most symphonic of Mozart's piano concertos. The Elgar was fantastic. Premiered six days after the death of Mahler, the symphony shares some characteristics with the 9th: a tremendous climax, at least in the second movement, some passages veering into atonality, and a very spooky third movement that ends in a frenzy. I really enjoyed the first movement. It starts out so recognizably Elgarian -- I thought I was listening to Enigma -- but then evolves into something that, in places, sounded more modern than the Diamond. I'm definitely going to illuminate this black hole of mine by getting to know these symphonies better. Next up, the highlight of the season: Mahler 9. Mitch Friedfeld
