This doesn’t come as a total shock or downer. If anything it’s a good time for Al to hang up the mic and enjoy his success a bit.
I also feel that Ministry’s last three albums were on par with their general modus–hard pounding industrial metal centering around political issues. Because they ended strong, I feel Al chose a good time to quit.
I think I liked them more for their message than their musical content. But yeah, everything must end.
