Video: The xx "Crystalised" on Last Call

I love The xx, there I said it, whatevs. I really hate how hard it is to get decent video of musical performances on late night shows, so here is there best there is of The xx on stupid Carson Daly's show that only airs on the moon at 3am. I am still confused about how there are so many people there... does he just send a camera crew out to a band regular show then play a song with a retarded into every time? Why am I so interested in how this show operates?
