Been listening to this since it came out. He doesn't sound like Chris Cornell all the time, but there are definitely moments when I'm like, "shit, I didn't know Chris Cornell sang for Diamond Head". Not early era Ultramega OK CC, which is his apex, Far Beyond the Wheel is legitimately one of the greatest vocal performances of all time. But later era Superunknown or Audioslave shit.
I like some of his other vocal performances on the album better, although I think the vocals are overall a little over produced.
