^^^I figure ANTICHRIST SUPERSTAR would fall under one of the best industrial albums, and if that was the category we were discussing, then i would choose DOWNWARD SPIRAL by NIN or even LAND OR RAPE AND HONEY by MINISTRY.
But, as far as the best rock album, I would probably have to say the Beatles White album, and I can't fucking stand the Beatles, but that album was really influential to a shit load of musicians.
