Well, here I am, trying to brag something from youtube.
He's TJ, a bored man in LA. He was trying to make a medley out of the simple chord progressions on guitar.
I have tried to use the same method he used when I jam with my friends. But totally, I SUCK!
anyways, here is his youtube post.... just click and voila!
