what is underworls really about?

and do they worship satan?

Wow! Personally, I think you should listen to at least some of a bands music before jumping into a forum with a question like that.

Here's a clue - I don't care what religion any member of the band has, and I don't care about yours either. Satan is about as relevant as Thor. Do they worship Thor? Don't know and don't care.
