Sian, Oysher, and Hiroko Y amamura's 'Champagne', the fourth single from Sian's Chaos album, is a formidable techno excursion that channels the genre's raw intensity with surgical precision. This collaboration fuses Sian's industrial-leaning production with Oysher's intricate sonic layering and Yamamura's deep-rooted Chicago house influence, resulting in a track that is both cerebral and commanding.

'Champagne' drives forward with a pulverizing bassline and stark, distorted synths, evoking the atmosphere of late-'90s rave culture. A subtle infusion of acid house elements adds a layer of historical depth, grounding the track's futuristic edge. The trio's embrace of controlled disorder-marked by glitchy textures and rhythmic unpredictability-gives the track a haunting, immersive vibe.
