Norweigan wildman Lassee Gjertsen has taken the YouTubes by storm. With his DIY Gondry-esque edits, hyperactive musical sensibilities and deranged Scandanavian looks, it's pretty easy to see why the video has caught on so quickly. But coolest of all is Gjertsen's complete inability to play either piano or drums -- his instruments of choice in the video. It's only through a manic edit session that he is able to translate his amateurish flailing into full-on virtuosity. Be warned, between the incessant jumpcuts and the Viking yelps, this video might represent a seizure risk.
