So, the video is Eric Clapton in concert, playing a guitar solo.
And the sound is some guy named Santeri Ojala playing an intentionally bad guitar solo that matches Clapton's movements. Maybe doesn't read as funny as it is to watch. I think it's pretty funny. I particularly like the drummer's drumming, which is atrociously bad, but which somehow perfectly matches his facial expressions.
I seem to recall seeing more than one band around town that this reminded me of.
