They bill themselves as a ‘mantra-rock dada pythago-cubist orchestra’ — a whimsical label for an experimental math-rock duo whose cult audience has started pushing them into the mainstream.
Performing under the names Khn and Klek de Poitrine, the pair present themselves as 333-year-old time travelers from another world. They wear polka-dot, pajama-like costumes and oversized papier-mâché noses that conceal their faces. The drummer’s drooping nose bobs against metronomic, tightly wound beats, a visual oddity that contrasts with the duo’s clear technical command. Their tightly arranged, foot-stomping songs pull from 1970s prog, experimental jazz, funk and punk.
Formed in Quebec in 2019, the band released Vol. I in 2024. Their wider breakthrough arrived in February 2026 when Seattle station KEXP uploaded a live studio session filmed at the French festival Trans Musicales. The video has racked up more than 13 million views on YouTube, and its comments have become a subculture of their own, full of repeated-view confessions and jokes riffing on the act’s absurdity.
After Vol. II they climbed to more than 2.4 million monthly Spotify listeners and launched a sold-out international tour with stops across the UK and Europe. Their profile even inspired a Google Easter egg.
Fans and critics point to musicianship beneath the shtick. Klek’s drumming is often praised as near-mechanical in precision. Khn plays a custom double-neck hybrid that combines guitar and bass with microtonal frets, while manipulating multiple effects with bare feet to loop riffs live — a foot, as one fan put it, ‘is basically the third member of the band.’ The microtonal tunings and skewed meters reinforce the duo’s alien, rule-bending aesthetic; listeners describe the music as a musical oddity or a surreal mathematical joke.
The masks began as a practical joke: a friend running a local venue needed a last-minute act, and the musicians — who had recently played there in a different configuration — slipped into disguise to appear as an anonymous duo. Though past projects left clues and online sleuths speculate about their identities, Angine de Poitrine insists on privacy; their website cautions that identity rumors are unverified and risk invading the members’ privacy.
Reaction has been intense and varied. Some treat the band as a playful novelty — ‘Do you do weddings?’ is a recurring tongue-in-cheek question — while others complain their music disrupts domestic peace. A controversial Sunday appearance on Quebec’s talk show Tout le monde en parle, in which they performed and spoke in an invented ‘alien language’ with subtitles, drew right-wing criticism accusing the public broadcaster of promoting spectacle. That backlash only amplified interest.
Their name, Angine de Poitrine, literally translates to angina pectoris, a reference to chest tightness; fans read multiple ironies into that contrast with the duo’s whimsical presentation. Many listeners hail the group as an antidote to glossy, computer-generated pop — ‘Eat this, AI,’ one poster wrote — and others have framed the band as refreshingly human: ‘They didn’t break the internet, they fixed it,’ read another comment. Some fans credit the project with sincerely affecting their lives, whether by provoking thought or simply offering fresh, provocative art that annoys some and delights others.
The two say they have played together since they were 13. What started as a costume gag has grown into an intentionally bizarre but tightly executed project that pairs serious technique with a playful, otherworldly persona.
