Ambient electronic group Crystal Castles used to comprise of both Ethan Kath and Alice Glass, but Glass has since left the band (rather acrimoniously), leaving Kath to cary on with a new singer (Edith Frances). They’ve released a couple of songs together — “Decide” and “Frail” — but today another new track, purportedly from their upcoming album rumored to be titled Amnesty (I), has hit the web.

Titled “Concrete,” the song’s a loud, frenzied piece of music that Crystal Castles have also been playing during their live shows. Hear “Concrete” right here (just, you know, translate the text if you’re not a native Korean speaker).
