EVGENY ONEGIN = about 9, although 2 of them would need a Court Order to reclaim and it's not worth it
I don't suppose one of those you
can get your hands on is the version with the Bolshoi conducted by Rostropovich (on Chant du Monde, LDC278 485,6)?
I have the Solti version; Rostropovich beats it hands down as far as I am concerned. You have only to compare the orchestral postlude to Act 1 Scene 2 to realise that Solti is playing half-heartedly, if that. I heard Netrebko's version of the Letter Scene on R3 on Saturday; Vishnevskaya, even in 1976, knocks her into a cocked hat for characterisation and technique.
I have the performance on LP; unfortunately, it is difficult to reproduce cleanly. The CD issue seems to be well nigh impossible to track down second hand (I've been looking for years, seen it once, and have kicked myself for not snapping it up ever since).
