On the topic of bands continiuing without the members who made them what they are, I think it's best if they change their name like what Black Sabbath and Sublime did. New Exodus and Cannibal Corpse dont come of as cover bands to me because they still have their most important song writers. If Alex Webster or Gary Holt continued on with new bands they would probably just sound like Exodus and CC.
