Oh, man, just play the start of Mahler 8. The sound is fantastic. I really like what I'm hearing on these samples. Even the tenor in M8 sounds OK (not great, but not at all bad either). I really like that Bychkov gets the First Nachtmusik in M7 up to 16 minutes, but also gets the finale in at 17:12. And I'm very curious to hear what John thinks of the start of M9. There's a lot of solo horn in the mix, and the solo hornist plays it just a tad flat in pitch (which I like). I'm reminded of Barry Tuckwell on Solti's L.S.O. recording of M9. I love how they dig into the start of the Laendler movement, with strong horn trills made audible (second movement). I think this might turn out to be a really get set.
