If you've been surfing around YouTube lately, you may have seen the devastatingly funny videos created by Finnish musician Santeri Ojala, in which he overdubs concert footage by guitarists like Carlos Santana, Yngwie Malmsteen, Steve Vai and Eric Clapton with his own, deliberately awful shredding. Part of what makes the parodies so great is that Ojala is himself a professional musician, and creates music that so plausibly matches the video that it's hard to tell at first that it's not real. The effect of Ojala's overdubbed skronking on the unbearable pretentiousness and pomposity of, say, Vai going to work on a triple-neck stringed monstrosity is the comedic equivalent of firing a cannon at the Hindenburg: Quick deflation and a fiery crash.
