Word comes from a Drawer B commenter that Crystal Castles “borrowed” a lot of their sounds from the Chiptune community (Lo-bat in particular) and apparently also appropriated the image of Madonna with a black eye from an uncredited artist.

“Crystal Castles has been getting a lot press using the image of getting sounds nobody did before by using modified old console chips and is somehow stealing the whole ‘concept’ that the chiptune community is based on, and now we discover that rather than thanking the very own ground of this, they actually ripped the guts of it.“

Tsk. Tsk.

On a positive note, this track by Lo-bat is pretty bad ass. I can see why Crystal Castles stole it.
