YouTube is a never-ending source of historic archive footage, creative short films and, well, lots of videos of cats.
The clip below found its way into my email inbox by way of Guitar World Senior Music Editor Jimmy Brown. While not much of a video, the audio portion is what's really special; it's Cliff Burton's solo bass track from the Master of Puppets instrumental epic "Orion."
According to its YouTube page, the video was posted in 2009, and the track was almost certainly ripped from Guitar Hero: Metallica.
Old though it may be, it's still too cool a find not to share. Take it away, Cliff!
