If you know anything about blues music, you know how good this album is regardless of whether or not you've heard it. Despite the two huge names, I've met a decent amount of blues fans that have never heard this, let alone know there was a lengthy, recorded collaboration between the two. Simply put, more people need to know about this album, which is why I'm throwing it up here. This session was originally recorded live for television in 1983 and was not put into album form until 1999. According to wikipedia, the dvd of this session will be released on September 28, 2010 (tomorrow).
So if you're in the mood for some guitar virtuosity and some good ol' howlin', give this a listen.
