Not directly related to the topic of this blog, but something of interest to serious listeners: The Wolf Fifth Archive of modern classical music apparently has been completed at Ubuweb. It's been there for years, but it took a long time for it to be completed. Lots of Stockhausen, Boulez and Cage and a little bit of everything else. Not a lot of Russian material, unfortunately. "Wolf Fifth was a modernist music blog, featuring out of print and orphaned classics," a note on the site explains.
Ubuweb also provides access to a similar site, The Avant Garde Project.
If you are familiar with Ubuweb, I suggest taking a look. The "Top Ten" lists on the home page are a good place to browse.
