Crystal Castles is an experimental electronic music duo from Toronto, Canada, originally formed in 2006 by producer Ethan Kath and vocalist Alice Glass. Known for their abrasive sound, blending elements of electronic, synth-punk, and noise, the band quickly garnered critical acclaim with their self-titled debut album in 2008, featuring glitchy production, haunting melodies, and distorted vocals that challenged the conventions of contemporary electronic music. Their live performances became notorious for their intense energy and chaotic atmosphere, with Glass’s confrontational stage presence and Kath’s dense, sample-driven instrumentals.

Over the years, Crystal Castles released three additional studio albums, pushing the boundaries of their sound while maintaining a sense of raw emotion and urgency. Despite lineup changes, most notably Alice Glass's departure in 2014 and replacement by Edith Frances, the band continued to evolve, influencing a new wave of electronic artists and maintaining a cult following worldwide. Crystal Castles’ impact on the electronic music landscape is marked by their uncompromising artistry, digital nihilism, and the enigmatic persona that has defined their presence in contemporary music.
