If the Rattle performances are the same as on the BPO digital concert archive, I’ve heard them. In fact, all of these performances are on there except the Dudamel M3. I’m sure it’s fine, but they REALLY should have included the substitute Lorenzo Viotti M3 from earlier this year. It was an absolute knockout. I totally absolutely do not have an illegal .flac rip of that if anyone (doesn’t) want it; feel free to (not) contact me about it.
Yes Barry, I. Fischer did M3 a couple years ago. I haven’t heard that one yet either but it’s in the archive.
From what I remember of what I watched: Harding M1 is pretty good, not spectacular. Nelsons M2 is pretty much how Barry described about the VPO one. Haven’t heard the Dudamel M3 or YNS M4. Dudamel M5 is generally very good: better than his commercial release but not as good as the NYPO radio rip (can’t beat the New York brass). I personally really like the cooler Petrenko M6, but wish it was S/A. Rattle’s M7 and M8 are surprisingly good, both better than his Birmingham recordings. And the Haitink M9 to me is also mostly very good, if a bit too ponderous.
