I know it's a political website but you can skip the politics -Bergian will especially want to- and go directly to http://newstalgia.crooksandliars.com/ . Type "jazz" in the search box and you'll be offered some amazing stuff. There were a couple of Ellington concerts that even the mavens on the Duke-Lym list serve hadn't heard. I don't know who runs this site but they sure know their music.
