This is my first attempt to post a recording, so let's see if it works. Here's an LP from around 60 years ago. The transfer to digital was made by Alan Bunting, from an LP loaned by Ben Cutler. A good performance by a conductor who is rather forgotten these days.
5 flacs in a zip file.

I hope you enjoy it!
Many thanks for this rare recording under the underrated Swoboda.
