I should flag a festival happening in Paris' Cite de la Musique, under the banner Lenine, Staline et la Musique.
A whole series of fascinating events will entertain Parisians from now until the middle of January. Apart from the big names: Shostakovich, Prokofiev, Khachaturian etc, there'll be chances to catch undeservedly lesser-known talents like Artur Lourie (who turns up in a veiled reference in Akhmatova's Poem without a Hero), Vladimir Deshevov, Nikolai Roslavets and Alexander Mosolov. Some of them are seen as 'one-work' composers (e.g. Deshevov, for Rails), so this will hopefully be a chance to correct that impression.

Also worth noting is the very impressive (256-page) accompanying catalogue (the cover is illustrated above). I had the pleasure of penning the cinema essay - the first page of which is on the left.
