hip hop music made almost exclusivly by white males for other white males. often called nerd-rap by people who find it pretensious and geeky due to the sometimes very abstract lyrics, which often (or in the case of the anticon collective, almost always) do not rhyme.
Anticon fan: "Yo, i'ma go listen to some avant garde hip-hop shit and read chemistry books"
a subset of what has been dubbed "underground hip-hop". music that fits this category must contain original and experimental qualities that aren't always excepted well by hip-hop heads.
Busdriver's on some original shit, but sometimes it's too far out there for me.
Yea, he does that avant garde hip-hop thing.
