Oooooooooooh, man. I'll take Lenny and Berlin every day of the week. He absolutely crushed that thing, and with Karajan's house band to boot. Second to none, in my opinion.
However, his version with the Concertgebouw takes my breath away as well. It's elongated to an inhuman degree of sacred tension...I can hear the orchestra and audience strung out like a wire. It can be torturous at some points, but so direct and inward, almost to the point it bursts your heart - a 9th that takes just about every demarcated limit to the wall. Not for everyone. And not an everyday sort of recording. I just thank god it exists.
I'm a big fan of the the 9th in its hot incarnations if you couldn't tell. The Walter/Klemperers don't do it for me like they used to.
