(AMBITIOUS HIPHOP) Aesop Rock's latest CD, Fast Cars, Danger, Fire and Knives, comes with a little book. The book is not great, but it is an admirable attempt to raise rap to the high condition of literature. Like a novel, Aesop Rock wants rap to be a total document, to capture or reflect a whole way of experiencing the world. If Public Enemy's dream was to turn hiphop into a political party, Aesop Rock's dream is to turn hiphop into a modernist (not postmodernist) practice.
