DeRogatis doesn't ignore Bangs' failings. But frustration led him to channel his manic energy into prose that consistently rang out with the uncompromised intelligence and passion of the best of the music he loved. Rock 'n' roll is an attitude. It's not a musical form of a strict sort. It's a way of doing things, of approaching things.
Writing can be rock 'n' roll or a movie can be rock 'n' roll.
It's a way of living your life.
