I like this Kasabian album cover: the wild, Dionysiac violence of it.
It reminds me a bit of this amazing cover from a few years back, from an Andrew WK album. I had the idea of a similar cover for my book, Philosophy for Life and other Dangerous Situations - a photo of me or someone else with their face really bruised and bloodied, like they'd just survived an earthquake. Not sure Rider Books would have gone for it!
On a slightly different note, I also like the trailer for the BBC 4 series, the Medieval Mind, which I think captures quite how trippy it must have been to be alive in that crazy era.
