I've never met anyone in real life who knows the author Phillip K Dick, although I suspect here on the gaming interwebz there may be quite a few fans.
He's a science fiction author from the 60's 70's, wrote novels like A Scanner Darkly, Minority Report, Do Androids Dream of Electric Sheep (later made into the movie Blade Runner), and my all time favorite, The Man in the High Castle.
Somehow despite having a lot of books made into movies he's slipped through the net of public conciousness. I owned Minority Report on DVD for two years myself before I realised it was based on a book.
And I would like to confirm that Powerman 5000 are awesome if you like that sort of thing. If you like Powerman 5000 I recommend looking up Jerk, another great band that no one has heard of because A) they're Australian and B) they broke up after a really short time.

Edit: Actually, speaking of great music that no-one outside of Australia has probably heard of, here are two awesome artists I'm into right now
