I'll make it short:
1. It is a Waldbühne concert (correctly identified by one of the reviewers here as "pops"). I wish that word had been present in the title, since it would have made my expectations more correct. I'm not a fan of the "pops" idea in general and of the Waldbühne series in particular.
2. The part of the concert that makes this worth watching is: Solberg singing Solveig's Song and Jansen's two pieces (Meditation from Thais and Saint-Saëns's Rondo Capriccioso). This is outstanding -- one just can't get enough of it. Rimsky-Korsakov's Scheherazade is good but not at the same level: despite a number of cute moments, it is not such a great piece of music, and the performance of it here was not the best I've heard, charitably speaking; not being a conductor and so for what it's worth -- it seemed that the conductor thought in short elements, like periods or something like that; the longer-scale view of the piece was lacking; there was no overall flow; it sounded kind of stop-and-go a bit, disconnected, a bit grating. Usually this piece has a heaving, billowing, swirling quality to it overall, but not here. The Nielsen piece was downright boring.
3. The beginning (Mozart overture) was OK, but I didn't care for it much. It's probably subjective, but with known operas, my musical brain "expects", as it were, the spectacle proper after the overture; its not being there feels strange.
4. The concert ends in a blast of germanic beer music that the locals apparently love, but I didn't. The last twenty minutes spoil the overall thing, imo.
So: Jansen and Solberg numbers: five stars, no question (this is the part I've watched many times). The rest between four and two stars. Rimsky-Korsakov being split in two didn't bother me (though it is unusual). This was done, I figure, to make the programme more varied, contrasting, less taxing on the lovers of german beer music. Sound and video are impeccable. I'll give the whole thing five stars for the sakes of the best on this DVD, but be forewarned, it's not all at this level. Well, somewhat depending on how you like teutonic boom-boom marschen and elderly, portly conductors jumping up and down in a baboon fashion in a classical-music venue.
