Cassian is an Australian DJ and producer whose emotional, melody-forward take on modern house and melodic techno has made him one of the defining voices of the current melodic dance music movement. Born Cassian Stewart-Kasimba and based between Australia and Los Angeles, he has spent the last decade building a signature sound rooted in cinematic melodies, warm analog synth textures, driving basslines, and the kind of long-building emotional peaks that have become the calling card of the modern melodic house and techno scene.

His breakthrough came through a steady wave of standout singles, EPs, and remixes that quickly earned support from tastemaker DJs and labels across the melodic house world, and through his long-running creative partnership with fellow Australians RÜFÜS DU SOL. Cassian has been a key collaborator on multiple RÜFÜS DU SOL projects — contributing co-production and songwriting work — and is signed to their globally respected label Rose Avenue Records, cementing his position at the heart of one of the most influential collectives in modern electronic music.
