Mine‘s getting so accustomed to cold showers that I a) absolutely do not mind cold water for swimming etc. anymore and b) could not enjoy warm or hot showers anymore. They just weren’t nice at all.
You are missing out. I'm not really a Tool fan, they are fantastic live. Seen them 4 times, each show was amazingly different. They are very talented musicians.
But you are absolutely missing out by not giving Lateralus at least a once over. It's a musical masterpiece. IMO it's their magnum opus and one of the great musical creations of our generation.
Also a prog rock/metal fan, and I don’t enjoy most of Tool’s work. There’s a few good songs but I like Maynard’s work as Puscifer soooo much more. Drunk with Power, Dozo, and Momma Sed are fantastic.
