it might not be the worst 5th. But with better choices out there on streaming I would probably listen to it once.
Oh, it's not my favorite either, but it's maybe not the worst I've ever heard. I have an OG from the Philips Haitink/RBO 16-LP complete box set and should compare sometime. It's still an important performance, since it took Bernstein on Columbia in the US and Haitink on Philips in Europe to revive Mahler's brilliance as a genius symphony composer.
I really like the HvK/Berliner reissue in the DG The Original Source series, but I imagine that is OOP/OOS by now.
