The VPO was excellent. They opened with Webern's Passacaglia - I'm not saying I enjoyed every bar, but it was much better than I feared. Strauss' Don Quixote was rather long, though interesting at times, particularly in the variation where a wind machine was used. In the second half, Zubin Mehta really pulled out the stops in Brahms' Symphony No. 4, and we had two Viennese encores.
The late night Prom was perhaps a bit of a disappointment, though I still enjoyed it: perhaps rather more Kronos Quartet-like (nothing wrong with that, but not really what I was hoping for). It was certainly interesting to see some of the oriental instruments, particularly the pipa and the sheng.
