Watch: Angine de Poitrine debut third member on a new song

Math rock band Angine de Poitrine have debuted a third new alien member, who played the triangle on a new track at a live show in Toronto on Friday.

The Québécois guitarist-drummer duo, Khn and Klek, were briefly joined on stage by a third member, who helped debut an as-yet-untitled song. The third character was clad in their same polka-dotted aesthetic, with a large box as a mask, two yellow ear-like antennas, a long black nose and a distorted alien voice.

The new song even featured an intriguing triangle solo from the new member. Fans on Reddit speculated that the track will serve as the theme song for a Québécois TV show, though that remains unconfirmed.

Angine de Poitrine have just begun the latest North American leg of their 2026 tour, which will include dates in Montreal, Brooklyn, Boston, Chicago, Los Angeles and Seattle, alongside festival appearances such as Corona Capital in Mexico City.

They have also recently announced a world tour for 2027, including stops across Australia and South America, European festival sets like Primavera Sound in Barcelona and We Love Green in Paris and a three-night residency at O2 Academy Brixton in London.

Meanwhile, on October 16, they played a headline set at Dublin's Vicar Street.

"The duo play with a tightness, propulsion and cohesion that would cause jaws to drop even if they took to the stage in a jeans and T-shirt," wrote Hot Press of the gig. "And those jaws drop even further when you realise they're doing it in these cumbersome, restrictive outfits.

So should they just ditch the gimmicks and let the music speak for itself (and give themselves an easier and less sweat-drenched night at the office)? Nah."

In April, the band released their second studio album, Vol. II, which peaked at No. 19 on the UK Official Albums Chart and No. 1 on the Rock & Metal Albums Chart.

This followed Vol. I, which they released in 2024, peaking at No. 3 on the UK Official Independent Album Breakers Chart.
