By way of the Listening Post, I found out about Wolfgang's Vault. What a collection of live concert streams and downloads. Wolfgang was Bill Graham, the legendary convert promoter from San Francisco (originally the Bronx), and one big section of the archives is his concert recordings. Another big section is shows from the King Biscuit Flower Hour (seems to be another Wolfgang's site) for those of you old enough to remember that FM radio show. Much of the archives are classic rock, funk, and R&B, but they seem to have a good selection of recent rock/pop.
