We already told you that Asher Roth’s your new favorite white rapper, and no matter how many albums Eminem releases this year, we might just have to strike through the “new.” We doubt any spot of juvenilia will match “Lark on My Go-Kart” in ’09, especially when you take this animated video into account: When the emcee declares “Ash Roth be the king of the blumpkins,” it cuts to him on a toilet, with a friend; watch him play Mario Kart and say “I’ll be the best racist,” then backtrack. But it’s not just the maladjusted kid in us that digs this — the rhymes are elaborate, the beat terrifically big and spare. Em, Beastie Boys: Baton, please.
