Ludachrist. I actually prefer Bangfest, but I can't find that shit on the YouTubes.
And for the nerds. I got negged on FoH I think for this one, not sure why, cause I think it's pretty fucking awesome. It's on Bangfest as well. Sounds much better on the album I have than YouTube. Bass hits much harder.
Edit: Oh yeah, and you can download his albums for free, too.
