Interpol is a band with an almost automaton sound. It's like if robots came alive to make music. So if any band sounds cold and murderous, because robots don't have souls, it's Interpol. Appropriately enough they have a song called Evil, it's got a smooth baseline, and although I normally try not to post songs that don't have lyrics that mention something horror/halloween related, I figure I'd make the exception since this just sounds eery. While still being upbeat, I mean, Carlos Dengler knows how to groove a bass guitar.
