Zander's M1 is now in my stack of CDs to be brought to a store as trade-ins. It seems well-recorded, and as far as I (a non-musician) can tell, is well-played. But it lacks, in my view, rhythmic vitality -- it doesn't swing (or rock, if you prefer). Instead, it seems clean, antiseptic, and inert.
I much prefer the Kubelik/DG version; I also like Tennstedt's live recording with the London Philharmonic; both seem to pulse with vitality. And I would never trade in the Giulini/Chicago recording of M1, which feels slower, and more stately, even grand.
My spouse, in her former corporate job, had to attend a presentation by Zander in his role as motivational speaker. She found him pompous and simplistic. I did not listen to the discussion disc.
