The Birthday Massacre is a synthrock band from Canada. They've got quite a unique sound. The best attempt I can give at describing it would be electronica mixed with metal-ish hard rock. You'd really have to listen to a song by them to understand. I'd recommended you check them out only if you're pretty open minded when it comes to music. I don't have much to say about them at the moment but I'll probably post a review of one of their albums in the future.
