There are at least 15 other recordings from 1982 that sound just as good or better than Drammen. Why do so many people want it..? Just because they can't easily have it?
First get the Zurich, Leiden, Frankfurt, Dortmund, Paris, Vienna, Leeds, Edinburgh, Montreal, Boston, New York, Chicago, Oakland, Fukuoka, Osaka, Nagoya, Sapporo, and Tokyo recordings first. They're all easy to find in great quality.
Now, if I get Drammen, then great... if not, then I'm not going to beg for it. The above recordings should keep me happy enough.
