Enjoyed my Russian history courses the most out of my college experience. Some have said that the Silver Age is so named because the Golden Age was better. I don't think that's true, just that the Silver Age was different in terms of Russian Culture and its development.
Others would say (and I think this is more accurate) that the Golden Age was more centered around musical composers, symphonies and novels, while the Silver Age was more focused on poets and playwrights.
Mostly we are talking about cultural history in the late 19th and early 20th centuries, before World War I and the Bolshevik Revolution. Playwright Anton Chekhov was during this time period, as was poet Boris Pasternak. Composer Igor Stravinksi is also considered part of the Silver Age.
The accompanying link does a nice job of identifying other artists and musicians that fit into that time period.
