Quebec’s renowned electric rock duo, recognized for their use of microtonality and math rock along with their trademark black-and-white, polka-dotted costumes, might just inspire your next Halloween ensemble. If you’re looking to stray from the usual costume options like salt-and-pepper shakers, you and your partner can now acquire the Angine de Poitrine couple’s costume from Party Expert for a reasonable price. These sought-after costumes quickly sold out online following recent media coverage but have been replenished as of the following day. Is this surge in demand an indication of the avant-garde band’s move towards mainstream popularity?
The duo, celebrated as an icon of human creativity opposing artificial intelligence, has garnered a loyal following for their commitment to eccentricity, spanning from their unique electronic sound to their claim of being 333-year-old extraterrestrial time travelers, not to mention their preference for conversing in a fabricated language during public appearances. For a total of $105, you can sport drummer Klek de Poitrine’s iconic white attire this Halloween, while an equal sum will secure your partner the guitarist Khn de Poitrine’s signature black ensemble.
When contacted by CBC for comment on the costumes, the band chose not to respond. Hailing from Saguenay, Quebec, the duo initially formed in 2019 and gradually made a name for themselves within the local underground music scene before releasing their debut album, “Vol. 1,” in 2024. Their unconventional style began generating buzz, but it was their live performance at the Festival Trans Musicales in Rennes, France, in December 2025 that propelled them to international fame. The performance, posted by KEXP in February and amassing 20 million views on YouTube, marked a turning point in their career.
Following their sophomore album release, “Vol. II,” in April, which received widespread acclaim, resale tickets for their 2026 tour surpassed $500, and they attracted record-breaking crowds at various festivals. Recently, the band clinched the Polaris Album prize and the SOCAN Polaris Song Prize for their track “Fabienk.” In a statement to The Canadian Press in July, drummer Klek expressed gratitude for the band’s unexpected success, attributing it to perfect timing and chemistry between the two members.
The replicated Klek costume is marketed as a standout choice for office parties or costume contests, ensuring that any duo dressed in these outfits will make a lasting impression among the traditional Halloween characters. While the costumes reference the band members by their aliases, they are officially termed the “Black/White Polka Dot Attack Costume,” without explicit endorsement from the band. Although the base costumes are priced at $59.99, the matching masks/hats are an additional $44.99, making it a relatively expensive costume choice. Not included in the package is Khn’s distinctive microtonal double-neck guitar.
While some fans opt for the DIY approach, others may find the price point of the official costumes steep and may prefer to honor Angine de Poitrine’s spirit of quirkiness by crafting their own versions using readily available materials and a touch of creativity.
