Tanglewood Festival, last week.
Concert 1: Haitink conducting the Boston SO in Mahler's 4th and Mozart's 5th violin concerto with Isabelle Faust. This is the second time I've seen her live and I really like what she does: beautiful tone, with a fresh and dynamic take on an old favourite. But the BSO occasionally seemed a bit pedestrian (bored?) in the Mahler.
Concert 2 was Mozart's 9th piano concerto played by an old pro (Emmanuel Ax) and Mahler's 1st, both with the Tanglewood Music Center (essentially the young musicians who have spent their summer studying there) under the baton of Christoph von Dohnányi. Like Haitink, von D. is a remarkably spry 84 year old. He got an amazingly good performance out of his orchestra, especially in the Mahler: big sound, a lot of soul and enthusiasm from the performers, lots of vitality from everyone. No chair or stool on the rostrum: he directed the whole thing in a very precise, didactic manner and the result was very enjoyable. Overall, I much preferred the TMC's Mahler to the BSO's. (Charming Swedish soprano in the 4th, though.) The Mozart was a bit less together: fewer musicians and fewer big sound effects, so I suppose there's no way to hide any small lapses.
