It would've been nice to see a bit more analysis of the evolution of their writing style, but they cover well the influences and circumstances that shaped them (make no mistake, this is not a typical 'sex, drugs & rock n roll' bit of worthless literature. It IS an illuminating read). Bound to appeal to any old-school 'head or Hellhammer/Celtic Frost fanatic for the sheer wealth of photos and background stories. Pretty inspiring too to read about just how naive but utterly determined they were back in the early days.
