Well while trolling through the vast gem mine that is videosift, I stubmeld upon these two blokes. They call themselves Datarock and you can view one of their more popluar songs off their album Fa-Fa-Fa. They can probably be best described as Electronic/Rock. The song below called Computer Camp Love is definitely Nerdcore in my opinion.
While I’m not terribly taken by the song lyrically speaking, the beat certainly is very catchy. They are touring in the UK area it seems, so all you Brits get a chance to check em out live.
