Quebec’s famed electric rock duo, recognized for their unique style blending microtonality and math rock while concealing their identities in striking polka-dotted full-body outfits, may inspire your next Halloween ensemble. Instead of the usual salt-and-pepper shaker costumes, you can now acquire the Angine de Poitrine couple’s costume for around a couple hundred dollars from Party Expert, a prominent party supply retailer in Canada.
Following recent media coverage, the costumes quickly sold out online on Tuesday but were promptly restocked by Wednesday morning. This surge in demand raises questions about the avant-garde band’s shift towards mainstream popularity. Embraced as a symbol of human creativity opposing artificial intelligence, their fans celebrate their commitment to eccentricity, ranging from their unique electronic sound to their claim of being 333-year-old extraterrestrial time travelers, and their preference for communicating in a fabricated language during performances.
For approximately $105 each, you can embody drummer Klek de Poitrine’s iconic white appearance or guitarist Khn de Poitrine’s signature black look this Halloween. The band refrained from commenting on the costumes when approached by CBC.
Originating from Saguenay, Quebec, the duo emerged in 2019, gradually gaining recognition within the local underground music scene before releasing their debut album, “Vol. 1,” in 2024. Their unconventional approach attracted attention, but it was their live performance at the Festival Trans Musicales in Rennes, France, in December 2025 that propelled them to fame. This performance, posted by KEXP in February, garnered 20 million views on YouTube.
Their second album, “Vol. II,” released in April, received widespread acclaim. Tickets for their 2026 tour were resold for over $500, and they drew record-breaking crowds at various festivals. Additionally, they recently clinched the Polaris Album prize and the SOCAN Polaris Song Prize for “Fabienk.”
Drummer Klek expressed, “We’re just two random people who enjoy playing together, and I feel we just took a wave, which was the right time at the right moment,” in an interview with The Canadian Press in July.
While the official costumes cost $59.99 each, the matching masks/hats are an extra $44.99, making it a relatively expensive but attention-grabbing attire. Some fans opt for a do-it-yourself approach, like Instagram user itsnicolaclare, who shared a tutorial in July on creating a Khn costume.
For those hesitant about the cost, creating homemade versions with spare clothes, paint, cardboard, and a dash of creativity could honor the spirit of Angine de Poitrine’s quirkiness effectively.
