I found this video thanks to Mark Hoppus' Facebook page so can't take credit for being a tastemaker of sorts.
Check out this guy "The Petebox" cover "Where is My Mind" by the Pixies. It will seriously blow your mind people because the whole entire thing is recorded live! There's nothing pre-recorded...
The info that came with the vid from Petebox:
"Here's my new vid - a cover of a song by one of my favourite bands. The track is made live using a guitar, beatbox, voice and an RC-50 loop station. The reverb on the vocals at the end is off a Kaoss Pad which only features at the end for the reverb effect (u can see 2 but that's to do a different track we filmed after!) There's nothing prerecorded or added post recording, it's all live! Filmed by Simon Elli"
