Apparently I’ve been living in a box because I have only just recently discovered Crystal Castles.
Their music has been described as “ferocious, asphyxiating sheets of warped two-dimensional Gameboy glitches and bruising drum bombast pierce [the] skull with sheer shrill force, burrowing deep into the brain like a fever”.
Basically it’s the kind of music your parents would listen to and promptly say something along the lines of “you call THAT music?” or “What is it with what you kids are listening to these days?”
Personally, I think Crystal Castles are an acquired taste. Once you achieve that, their sound is insanely good.
