I can very vaguely remember this band?

Yes, as I said, VERY VAGUELY xD Anyways...I was listening to music on Youtube (who doesn't!) and this band was in the Suggestions. They're a five (?) piece rock type band, fairly new. I think the video was pretty new too..maybe last year or something :S Anyways...I don't remember a word of the song..but I can sort of remember bits and pieces of the video.The lighting was kinda dark-ish and moody..a bit green.and they were just basically rocking out in what looked like a multistory car park... :S Random people were running past them...and gradually more and more people just come from nowhere, till there's like a huge crowd just running past them while they're doing their thing.

Have you got any ideas who it might be? Any help is great!
