Get the crystal castle mug.
An electronic duo from Toronto, Ontario. Like many indie bands, the main appeal is that no one has heard of them. What Crystal Castles has over them, however, is that they are so shitty they will never become popular. They are a hipster's wetdream.

A band with a singer that can't sing deserves no respect.
