The 7th seems to alternate between day & night and is all about "mood". This said, I prefer Bernstein’s 1966 over Klemperer’s --even though it’s faster it seems to be better at bringing out the moodiness.
I heard another superb live performance with Sir Simon Rattle conducting the Berlin PO (I think)-- recorded in the late 90s
Finally there's Tennstedt's live recording from the early 80s, nice but not quite up there with the others IMO.
