Last year, I went to Rock im Park, a pretty famous German Rock festival. While I was there, I heard "Tool" play live. Ever since, I have been listening to their music off and on, and I've discovered that they are one of the few groups that make the kind of music that manages to actually do more than just sound nice. Their songs paint pictures, make you feel... whatever the song is about. It's not the head-banging-inducing euphoria, I get that with other groups, too. It's something else entirely, and it's both very creepy and very, very cool.

If you fancy a listen, here are the links to a few of their songs:
