Nowadays, we almost expect bands who benefited heavily from the Internet hype machine on their debut to fall short with their follow-up. Not Crystal Castles. The Toronto natives made the best song of their (short) career instead. Ethan Kath's production has matured into something more structured than the spastic Atari blips of their debut and Alice Glass drifts into pop territory with her vocals and nails it. The tune definitely surprised us, but it's clear that in the case of "Celestica," change is good.
