Shostakovich Sym no.8- Previn conducting the London Sym Orchestra (Angel);
Shostakovich Sym no.10- Yevgeny Svtlanov conducting the USSR Sym Orchestra (Melodiya).
Having listened to them back to back tonite, I can tell you that the Angel is the better recording cause of its more faithful rendering of an orchestra in a hall. Of all the Shostakovich Symphonies I've heard, the 8th also happens to be the one I love most.
