Enjoyed leafing through this at the Taschen bookshop on Sunday. A lot of it is a bit baroque but there are also some amazing structures from what I assume is a fairly uncharted period in a fairly uncharted region (ie Russia just before the collapse of communism). See also Richard Pare's 'The Lost Vanguard' for a relatively sober comparison!
I was given a few names recently of notable contemporary Russian architects and the only one I've investigated so far is Alexander Brodsky who created a series of drawings with Ilya Utkin mainly in the 1980s, often submitted as entries to architectural competitions in Japan and the US. Well worth a look, particularly if you like Boullee, Piranese etc
