“The last 10 months in Chicago have been grim for the classical music compact disc collector.

The hopes of aficionados soon rested with the Michigan Avenue Virgin Megastore, but with only a moment’s notice, it closed for business in July. Now, as online file-sharing makes the compact disc primitive, local classical CD buyers are wondering if the brick-and-mortar classical meccas are just a thing of the past.”
