Fine work - I like the Tortelier recording with Paavo Berglund conducting I think.
Here it is in a fine inexpensive set as the Mackerras version of Symphony 1 is excellent too:
Wow! You must have a huge record collection! I can't afford to buy multiple recordings of the same work; or rather, I prefer to get something I don't already have. So it's pretty much Naxos all the way down. I live on a remote island near the Alaska panhandle so shopping can get inconvenient (I'll be here for another two years...)
I'm very impressed with the 2nd S. as well. I streamed the 1947 SQ as well and that's a terrific piece. All too often composers fall into the pattern of writing overly contrapuntal and chromatic string quartets...as if that's the only sound that can be conveyed through the group. Like Barber and RVW, Walton makes good use of lyricism and rhythm in the quartet.
