At 7:46 this comes close to the Bruno Walter timing, who was otherwise a conductor quite well 'feeling' Mahler. My personal taste goes out to a performance in a clip from the 1971 movie Death in Venice, and that lasts about 9 minutes. Now that one is absolutely wonderful. I consider it definitely better than the version above, but I wasn't able to find it tonight. Perhaps it's better so, since the clip is somewhat controversial, and my feelings about that movie are a bit ambiguous. Death in Venice has been lauded by most culture popes to such an extent that it's almost impossible to hint you don't feel too comfortable with the homoerotic/pederastic nature of the movie. Our moral bettes will inevitably come up with something like that it's a movie about the discovery of beauty, regret about beautiful things forever gone and the like. I don't know. Perhaps I should see it once in whole and then judge.
Anyway... yes, the Adagietto has been commercialized thru and thru. You will find it on a gazillion "Most beautiful classical melodies EVAH" and so on. Still, that does not detract from it's heartbreaking beauty. Enjoy it. And thank you, Gustav Mahler.
