I'm a huge Paul and Annie fan. This is a couple of years old, so somebody here may have posted it before, but it's new to me. Some good Son House stories and historical anecdotes in this lecture/concert. Of course, watching them play is the best part. If you've got really good eyes, you might even steal a couple of licks. Definitely worth checking out.
