For 2012's more streamlined III, the duo decamped to Warsaw, where they recorded direct to tape, eschewing any computer-assisted recording.
Glass left the project in October 2014 to pursue a solo career; in April 2015, Kath resurfaced with a new Crystal Castles track, "Frail," which featured new vocalist Edith Frances.
"Alice Practice" was released as a limited-edition 7" in summer 2006 on Merok Records, also home to Klaxons; its 500-copy run sold out in three days.
Kath and Glass worked on their own songs and also honed their remixing skills, tweaking songs for Klaxons as well as Good Books, Uffie, Health, and Bloc Party.
Fusing lo-res electronic noise and pop hooks so effortlessly that it can seem accidental, Crystal Castles began as producer/multi-instrumentalist Ethan Kath's solo project in late 2003.
Tours with the Presets and Metric in 2007 set the stage for the release of Crystal Castles' self-titled debut album, which Last Gang released early in 2008.
The duo returned in 2010 with another self-titled album; when it leaked onto the Internet in late April of that year, the band released it digitally soon after, with a physical release following that May.
