Summary
- Angine de Poitrine performs as 333-year-old alien travelers.
- Their microtonal sound uses pitches between standard musical notes.
- The duo gained viral fame after a KEXP festival performance.
Khn and Klek de Poitrine, the enigmatic duo behind Angine de Poitrine, have captured global attention with their distinctive "mantra-rock Dada Pythago-Cubist" sound. Performing as 333-year-old alien travelers from Saguenay, Quebec, they utilize microtonal music, employing pitches outside the standard 12-tone Western scale. Khn plays a custom double-necked guitar and bass, layering riffs using a looper pedal, while Klek delivers complex drumming. Their anonymity, originating from a desire to avoid audience fatigue in 2019, is maintained through elaborate papier-mache masks and their signature black-and-white polka-dot costumes.
The duo's viral success began when KEXP recorded their performance at the Trans Musicales festival in December 2025, with the footage gaining massive traction online after its February 2026 release. Clips accumulated tens of millions of views across platforms like YouTube and Instagram, sparking widespread analysis of their unique musical techniques. Their international appeal was further cemented with a U.S. television debut on The Tonight Show Starring Jimmy Fallon, performing their new song "Zugzegk."
