Biffy Clyro - Mountains + Many of Horror

Living in Edinburgh was good for so many reasons, one of them being the discovery of Biffy Clyro. I remember reading someone saying that after Puzzle the media decided Biffy Clyro were fashionable now, even though everyone else had thought they were amazing for years...
I've been trying to decide all day nearly which song to post.... Mountains or Many of Horror... then I decided to post them both, because Mountains has been my favourite for at least a year, and the second half of Many of Horror is the best minute-and-a-bit of music I've heard in a long time... I think people like the first bit because it's very ballad-y, but I'm not such a big fan... anyroad...
