I'm not really a Hendrix devotee, but I wanted to read some Tate and this is what the library had. Tate's goal is to reclaim Hendrix for black folks, and he does this in ecstatic, lyric, highly referential and jazzed writing. He lays out a dozen different genealogies of black culture that Hendrix sprang from, whether musically or socially or artistically, etc. It's mostly a tumble of impressive words, though at the end, there are essentially transcripts of four interviews with people who Hendrix in different ways that are are very restrained but interesting.
I think maybe Tate's charm is the mix of his over-the-top style and his interesting choice of sources? It makes for an impressive, if quick, read.
