From Wikipedia: Crystal Castles is an experimental electronic music band from the province of Ontario consisting of producer Ethan Kath and vocalist Alice Glass. Crystal Castles are known for their chaotic live shows and their lo-fi, melancholic home productions. To listen to Crystal Castles, according to the BBC, "is to be cast adrift in a vortex of deafening pain without a safety net. You get the feeling you could do anything in the world, but that 'anything' would ultimately mean nothing. Crystal Castles marks a nuanced emotional territory that dance music never covered before."
Crystal Castles were named after the lines "The fate of the world is safe in Crystal Castles" and "Crystal Castles, the source of all power", both lines referring to fictional character 's fortress in the sky. The band was formed in December 2003 as a solo project started by Ethan Kath. Ethan Kath later discovered Alice Glass singing in her noise-punk band, and thought he had found the "missing ingredient" to his music. He asked her to record vocals over his solo instrumental tracks. In April 2005, Alice Glass recorded vocals over five original instrumentals by Kath. The microphone test for this recording session was secretly recorded by the studio's engineer and was later released as the band's first single, a limited edition 7" vinyl on London's Merok Records, released in June 2006 and sold out immediately. Glass was not aware the microphone test recording existed until Merok Records asked to release it.
