URB has a feature on Busdriver. Check it out, it has some stuff on his background I never heard before. More importantly it does a good job at describing his aesthetic. Link
“This isn’t just weird rap done by weird rap kids,” says Bus. “This is done by grown black men. I don’t think people really get it. People have painted the picture of the backpacker and the college hip-hopper; the scrawny little nerd huddled over, writing notes and talking to himself. But it’s different. It draws from other things. The history of underground rap is something people neglect, but it’s deep. I don’t think I’m advanced. I think that what I do is old school, actually. I just take what was advanced in ’94 and apply it to now. I thought that’s where we were.”
