I came to this recording shortly after listening to Rostropovich's earlier version of the work with the National Symphony Orchestra of Washington (on Teldec). The differences are not as great as I would have expected; this is very much heart on sleeve Shostakovitch, and both discs give us performances played for all it's worth. The Teldec has a more spacious recording, but the LSO Live taping is technically their best so far (they record live in the Barbican Hall, London-not a very sympathetic acoustic). In the last movement, though, I think the London players have the edge in sheer,well,-power! And on the last chord, as before, Rostropovich lets the bells play on, an effect some critics don't like but I think adds to the fevered atmosphere.
An incredible bargain. (Try getting a seat for that price)!
