So this looks pretty damn interesting.
That's worth mentioning in its own right; but it gets better. Rather than just making do with a standard hardcover book, Cave has also created a deluxe box set featuring an audio CD version, read by himself, which includes a soundtrack by he and his long-time collaborator, the largely-bearded Warren Ellis. On top of that, there's also a download version, which has been especially mixed to be listened to on headphones. Smart eh? And according to this Guardian article, the download version includes an enhanced edition available as an application for the iPhone, which you can both read and listen to (though there's no sign of it on iTunes at the time of writing).
And heck, they're not done there, as there's also a signed, numbered, limited edition slip-cased edition being made available exclusively through the book's microsite, where you can also check out audio samples of the book/soundtrack, and video clips of Cave reading.
It feels like a fantastic mash-up of formats (the marketers might call it convergence), perfectly suited to Cave's polymath tendencies. Here's a man who's made (often incredible) music, lectured on love, written a novel (And the Ass Saw the Angel, being re-published at the same time as Bunny Munro), and who even wrote the screenplay for a fantastic movie, The Proposition.
It's a frankly disgusting amount of talent for one man.
Looks like there also might be some kind of tour – you can sign up for news on the site.
