I posted a thread like this, and everyone suggested different albums.

With tool, its all really great, so just pick one, decide what you like and dislike about it, and then go from there.
Undertow might be their most accessible so try that first. It's "angrier" than their other ones I guess. But if you want "artsier" Tool go with their latest album.

Don't listen to it too much. They become lame when you listen to it so much that you realise how cliched and 'progressive' they really are
Who reads sigs anyway
'Aenima', it's their best.

Why do we feel it's necessary to yak about bullsh*t in order to be comfortable?

That's when you know you found somebody special. When you can just shut the f*ck up for a minute, and comfortably share silence.
