Deryk and Karl recommend Furtwangler, Scherchen, Kleiber and Bru"gen.
I'm waiting to find a clean box set on the Seraphim label of the Furtwangler
Beethoven. I know Seraphim isn't the greatest quality, but I don't have
the $$$ for original pressings. (OT, but if any of you have the first
English HMV pressing of Furtwangler's 9th, I suggest you put it in a
safe deposit box.)
I found two very good copies of the Beethoven 3rd and 7th with
Weingartner/VPO on the Columbia "Entre" green label. Many raves
about the performances, (from '35), including a MCML local, Scott Morrison,
but not much enthusiasm about the Entre pressings, lol. I'm not mono-phobic
anymore, but from '35?? Yikes!
BTW: Did anyone try the '50's Juilliard Bartok String Quartets, as they
are available now for the first time in decades on CD? I'm still reeling
from these performances.
