You might remember a bizarre story floating around entertainment websites and blogs last summer: some rapper was writing a mix tape devoted to what? Seinfeld? Wale's Mixtape About Nothing, which contains quirky catchphrases and the voice of Julia Louis-Dreyfus, is a compilation that critiques the current hip-hop world in a sardonic Seinfeld tradition. Think Kramer (played by Michael Richards), bobble-headed and crazed, meets a scathing review of Richards' onstage racism. Now touring with UCB and Colin Munroe, Wale brings his Attention Deficit Tour to Northampton for a night of fiery hip-hop and rap.
