A couple of guesses...
King Diamond w/Abigal?
Goatwhore may have played their last album during their support slot on the Celtic Frost. Granted I don't their music memorized, it sure sounded like they played all new stuff and the new stuff is only 40 minutes long.
GWAR is definitely playing their last album on the current tour.
Jaco died for our sins so that modern bass players could be free to play more and be heard.
