Finally, I have a good forum to post about this on!
Adam Warrock is a nerdcore rapper, and his last album was a seven-track piece about Akira.
I met him at Emerald City Comicon this past year, and he's a super cool guy. He used to be a lawyer in D.C, decided he hated it, and went to pursue a career in hip-hop instead. Like I said, super cool. Even if you're not into hiphop, it's worth checking out.
