How-to play L4D2 Hard Rain theme

I received several requests for a how-to video version of this particular piece, that I recorded for the soundtrack of L4D2. Note, as I explain in the video, I have my guitar tuned to an open E minor. The original piece was recorded in open A minor. Due to the challenges of tuning my guitar as I did for the original recording, I chose to share this in E minor, which will be the easiest key for the majority of those interested in attempting to adapt these ideas.
