I'm sure many already caught the hardcover last year, and/or recently shelled out for the upcoming Nick Cave book.
But should you find yourself in need of more Bad Seeds genius right now, this one is set for next month, at £10.99 plus shipping, just a few days ahead of the Cave, and I think it somehow hasn't been posted yet.
