18th September, COSMOS returns to The Back Room.

For this one, we welcome Oshana to Bali for her COSMOS debut.

Oshana is a sonic architect blurring the lines between house and techno, combining intricate percussion, raw energy and futuristic soundscapes into a sound that is unmistakably hers.

Since breaking through in 2012, she’s released on Fabric, shaped labels including Partisan and Pillz, and launched her own imprint, Psionic. From Robert Johnson and Concrete to ADE, Off-Sonar and Epizode, she’s brought her sound to some of the world’s most respected dance floors.

Joining her is Ace Vision, the Berlin-based DJ and producer known for long-form journeys through hypnotic, driving rhythms, moving fluidly between techno and house. Drawing from the electronic sounds and textures of past decades, his sets balance raw energy, atmosphere and emotional depth, creating immersive journeys that connect deeply with the dance floor.

Completing the lineup is Archie, a key figure in Jakarta and Bali’s underground scene. A member of SCRUBS!, Fraktal and resident at Klymax Discotheque, Archie’s sound is shaped by punk, experimental electronics and rave culture, sitting at the intersection of minimal tech house, acid and mesmeric grooves.

Three artists. Three perspectives. One deep, hypnotic journey.

18th September. The Back Room.

Come ready to get locked in.
