HappyBlox did this mash-up of 2 classic pieces of media - It's Tricky by Run-DMC and the film Escape From NY. Besides HB's stylized editing, it is a pretty good combo! Especially towards the end when Isaac Hayes steps into the picture.
A to the B schooled me on these mash-ups, Radiohead vs. Jay-Z. I would have liked to see some vids, but the tracks themselves are pretty badass. There seem to be a few out there but these are some of my faves. Enjoy. UPDATE: You can download the whole album here.
