Good to have you here! We're currently compiling a list of songs to teach on the site and have to get clearance from the publisher to keep it legal. There are some great blues songs that I was looking at today by instructor Nick Marchant: http://www.guitartricks.com/lesson.php?input=8926 when I was looking for some slide guitar techniques.
I'm going to ask Christopher Schlegel to stop by and fill you in on the theory details...yes, plenty to choose from!
