Even though the early M8 recordings (Abravanel, Bernstein, Haitink, Kubelik, and Solti) were all studio recordings, nearly all live recordings of the work after those five sound so much better as performances, not as big blast fests. I know that there are a few recordings after those initial five that were recorded as studio ones, but I don't know nor particularly care what those are. I'm quite happy that the recording by Philly/Nézet-Sëguin observing the hundredth anniversary of the work's first performance in America was a live recording, and that has the intensity as to how the work should sound. Musical. Not a blast fest. And I'm so happy that I was at that performance! You could feel how charged the air was in the Verizon Hall at the Kimmel Center (Verizon Hall will shortly be renamed/rededicated as the Marian Anderson Hall) when the performances took place.
