Bottlerocket - yeah they ended up with a slightly weird reputation they didn't deserve, from a couple of guys they fell foul of. "Creative differences" etc, etc. It probably stuck just 'cause they don't really do enough media to neutralise stuff like that in the eyes of Joe Internet. So it goes in the big leagues I guess - if you're not enough of an asshole to "work on your branding" people will just assume you're an asshole by default.
Wouldn't want to have to argue with Win Butler or anything - dude's a lot bigger than me - but those guys are the real deal for sure. And a hell of a lot funnier than their press shots would suggest.
