I'm a pretty die-hard prog guy, but I'm not really into Tool. I think MJK is his band name, and while Justin Chancellor is a killer bassist, their songs have never really done it for me. I don't know, just kinda repetitive. The fans, though, absolutely killed it for me. I don't know if any of you are into indie games, but it's a similar thing to Undertale: it's not bad, and while it's not my cup of tea I'm interested in trying it, but the fanbase is so rabid and "this is literally better than sliced bread you uncouth moron" that I'm pretty happy staying at a 10-foot pole's distance.
Happy people writing articles about Tool don't have to put ". . .their latest album, 2006's Lateralus. . ." in said articles anymore though.
