Crystal Castles is by and large unlistenable for most people. I mean, more unlistenable even than what we usually post here on a daily basis. CC actively aurally assaults you. It's like an NES finally got fucking pissed enough at you for shooting light guns at it for days on end in the 80s that it decided it wanted revenge. In an evil, evil way. Ostensibly there is singing in these "songs" but in reality it's just banshee screaming on top of all the rest of the noise.
But this - this is Crystal Castles made listenable. CC and Robert Smith of The Cure somehow produced this actual gem of a song. It's so emo, it's even cute! Don't worry, I'll post real CC later.
Edit: for title context, here is CC's excellent song from their first album, the ever-so-common-for-debut-albums name: Crystal Castles. (Their second album's name isn't any better, the cleverly titled Crystal Castles II).
