Of course there's video trickery going on here, but you'd be surprised how many people in the YouTube comments for this splendid little video didn't catch that at first. Guiz de Pessemier, aka GuizDP, filmed himself playing the Tetris theme five different ways on guitar and then edited them together into this masterful creation.
The video, which popped up last month, is a parody of Walk off the Earth's famous cover of the Gotye song "Somebody That I Used to Know", a terribly catchy little tune that I've only just recently discovered. Be careful watching that one; it will stick in your head like some incredibly sticky analogy that I can't think of at the moment because the song won't shut up.
GuizDP captures the spirit of the cover perfectly, right down to the middle guy's intense stares directly at the camera, as if to say "I'm about to rock your world and then sound like crap on Ellen". It's a very specific sort of stare.
So thanks, GuizDP. You've made me believe that one day I can be as cool as the bearded guy on the right.
