Also a good interview where they talk about the track:

Did you guys ever do I live?

No, no. That whole track was written and recorded just on random. Me and Fredrik would just jam on something, and when we found something that was kind of cool, he would walk into the control room. I would just record drums and it wasn’t a set pattern, I would just kind of stray away from the pattern, but just keep going in that vibe. Then we had to chart everything and go bar by bar to record the guitars afterwards, because it’s all just random.

In doing it that way it’s also really, really hard to learn it. Even for us. I know parts of it, just because I’ve listened to it a lot, but it would be an awesome challenge to try to pull that off live, and it would take a shitload of rehearsing to get it down.
