I really like the loop feature. It helps greatly with learning the idiosyncrating parts of the tune. 

I also like that you've taken the time and effort to include links to original and classic versions of the song.

It's also great to hear Duke's thoughts and recollections of seeing the legendary Freddie King perform live. These are valuable insights for any serious player. It's not just about the notes. What's going on in the mind of the performer can sometimes be equally important.

Thanks for a very insightful lesson.
