That was great, and seriously a lot of surprises! The video was pretty confusing in places (like I imagine a bad-ass acid trip to be), and some contributors are almost inaudible, but overall it was very helpful. I was surprised by Springsteens contribution (great), and I also liked Orianthi's and Bonamassa's parts a lot (although they are players I normally don't care for). Tom Morello's part too is fantastic.
I said earlier it would be a one-time listening experience for me, but with the video it takes on a whole different dimension. Will listen and watch again.
