I am not a fan of rap, so I dunno who this guy is, but apparantly he died and Buckethead made a tribute video.

Note that Buckethead isn't talking, his puppets are. Buckethead never talks, he usually has Herbie (his chicken puppet) talk for him, but I think it was Herbie who was filming, so those other heads were talking. Anyway, there you have it.
