Well, I was a bit disappointed by the LPO/Isokoski. I could hardly hear her above the orchestra in the first song. Maybe she has lost some of her power, or maybe the LPO under Jurowski just played too loud. I have always wondered about the balance in these songs between a huge orchestra (the LPO brought out a monster last night with 8 double basses, 4 flutes etc.) and a single soloist, and on this occasion the balance felt wrong at least from where I was sitting (about 9 rows away from the stage, well to the right). Perhaps the acoustics of the RFH didn't help. Isokoski sang with a lot of emotion, and the 3d and 4th songs in particular were beautiful as Jurowski managed to keep the orchestra quiet enough so we could hear her.
The other weird thing about the program was that all the other pieces (2 Mozart serenades, very charming) and the modern piece of the evening (Magnus Lindberg's Gran Duo, very good and well done by the LPO wind players) were all for small chamber ensembles. So I don't even get the economics of getting the LPO out in full strength for 4 short Strauss songs just for them to rather overwhelm the singer for 15'.
