Currently I've got a friend newest midi playing on loop. But otherwise it's either the White Stripes Icky Thump album or the Takatalvi album by Sonata Arctica.
However, I was just on holiday in Dorset (a beautiful part of England by the way) and dug up an old Queens of the Stone Age album - Songs for the death. Oh my word, what an album! It's creative, it's gritty and has a truckload of mosh inspiring riffs. Really worth checking out, if you've thought about QotSA but never actually tried them. Chances are it won't be quite what you expected, but keep with it for a few listens and you'll be hooked. Plus the Radio fill ins are hilarious!
