Whun (not Wha) Chung of course...
And I second Barry's thoughts on the quick tempo. The sound of the Staatskapelle Dresden is beautiful indeed. It takes me back to my first Mahler on disc ever: M1 by this orchestra with Hiroshi Wakasugi. I thought it was very good at the time (some 25 years ago). Will have to revisit it soon, wonder if it still suits me...
