Now, I have the Gould DVDs which include Schoenberg, Berg, Webern, Scriabin, etc., the Goldberg Variations (from 1981; incredible technique), and all including his always interesting, yet odd and overly pedantic, opinions and observations. I love hearing musicians discuss music.
Last night I found on Amazon the Deutsche Grammophon pressing of Brendel with the BRO . Along with Schoenberg it includes Berg’s Violin Concerto. I had to refer to my Grammophon Good CD Guide to make sure that this pressing sourced the original VOX (1959 or thereabouts); it apparently does. At least one other label covers this, that being Universal Classics. I have no idea how the sound compares between the two; unless you know, I’ll google about for reviews to nail down a label.
I’m only familiar with the DG vinyl, which I picked up some 45 years ago. (I wore out the vinyl years ago, though - I now have a CD with Brendel playing with another orchestra.) The Berg concerto wasn’t included, just Schoenberg’s Violin Concerto with Zvi Zeitlin doing the honours as soloist. After checking on Amazon, I see they had Henryk Szeryng as soloist on the Berg concerto. That sounds familiar: I may have it kicking around on a different compilation.
Brendel’s performance with the BRSO is on YouTube, however:
