I had a couple of mates at school around 96/97 that were obsessed with Tool. Over the years I've met many people that seem to worship this band and seem to believe that they are above other people by appreciating Tool's work, seeing it as different, and some kind of special artistic stuff. Not saying all fans are like this but it is a theme I have seen.
I get that Tool feature deliberately less common time signatures and are fairly progressive requiring more of an investment from the listener to get into.... However, every thing I ever heard from them at the end of the song I can't remember anything about what just happened. It leaves no impact with me whatsoever. I just cannot get into it. I guess I just don't get it. I have tried. And that's fine. Glad so many like them and enjoy it! I love music and I guess this is why.... It moves different people in different ways.
