The Guardian reviews the sold-out New York debut of Angine de Poitrine, a Québécois experimental duo whose microtonal, odd-metered take on hard rock and elaborate masked costumes made them an unlikely viral sensation earlier this year. The band played two shows at Le Poisson Rouge, both sold out for months after a studio performance video posted to KEXP's YouTube channel spread widely online, and the review finds the live performance more than justified the hype, delivering the band's precise, unconventional sound with genuine spectacle.

The 700-capacity venue hosted the duo, known by stage names Klek (drums) and Khn (guitar/bass), whose viral video is nearing 20 million views. Their new masks now light up, adding a fresh visual element to their signature black-and-white polka dot costumes, and the set included tracks such as Angor, Yor Zarad and Tamebsz. Partway through the show a broken string on Khn's custom two-necked, microtonally fretted instrument tested the band, underlining the technical difficulty and improvisational risk behind their tightly constructed songs.
