Topic: 100 Riffs (Video)
This is pretty cool.
A guy plays 100 guitar riffs back to back which covers a "brief history of rock and roll". A couple of things:
1. He does it in one take (no cuts), and
2. There's a scanner below the video which shows the tablature of what he is playing in real time. So if you ever wanted to learn any of these, this might be a good resource.
