The Proms this year is featuring performances of all the Tchaikovsky symphonies, and earlier this evening concluded the concert with probably my favorite of them, the 4th. The BBC National Orchestra of Wales, conducted by Jac van Steen, presented a very energetic performance. Available for 7 days here on the iPlayer site(fast forward about 44 minutes to the beginning of the Tchaikovsky).
