Well here is my contest entry. Not much playing and I kind of ramble a lot so I hope it's coherent, but I talk about Lesson 20 and 21 about the pentatonic system and chords relating to it. This subject was the first one where I had a 'mindblown'-experience once I understood how it worked and how it all fits together with the CAGED system. Also I talk a bit about how I got into guitar initially, how I got back into it and what I want to do with it. I hope you enjoy :)
(also to those wondering why I keep looking to the side: I made some notes to make sure I didn't forget anything :P)
