Angine de Poitrine's Vol. II is a microtonal rock album released in 2026 by the masked Québécois duo Khn and Klek de Poitrine from Saguenay, Quebec. The album blends acid techno, disco, psychedelic rock, and progressive rock, all unified by the defining characteristic of microtonality. Khn plays a double-neck guitar tuned to notes that fall between standard Western tuning, creating a buzzing, alien quality, while Klek handles percussion with drum machine precision yet retains human swing. The band's official bio describes them as disciples of rock deities exploring the excess of rock music, and they perform wearing papier-mâché hats and polka dots while speaking only their own invented language. This sophomore record, following their sold-out 2024 debut that gained international attention through a KEXP performance, represents a more confident evolution of their sound with bolder structures and increased vocal elements. Vol. II pushes the microtonal sound further, featuring densely layered loops that build and shift, adding and removing elements until reaching controlled explosions before resetting. The album showcases sharper dynamics and demonstrates their trademark technical proficiency combined with genuine humor and groove that makes the complex music remarkably danceable. Vocals appear as interspersed moments treated as instruments rather than traditional song elements, with wordless exclamations and layered calls woven into tight grooves. Most tracks run approximately six minutes, creating immersive sonic journeys that range from high-tempo playing around 200 bpm to psychedelic nightmare soundscapes. The duo have become a phenomenon, gaining recognition from prominent YouTube music channels for their distinctive and uncompromising approach to composition and performance, successfully balancing style and substance while poking fun at over-the-top rock techniques.
