Angine de Poitrine performs an experimental, microtonal math‑rock concert at the McMenamins Crystal Ballroom in Portland, Oregon. The masked Quebec duo pairs intricate, looping double‑neck microtonal guitar work with precise, pulsing drumming to create high‑energy, mostly instrumental pieces. The show is notable for the band’s distinctive costumes and DIY microtonal instrumentation that have driven rapid critical attention and viral interest in recent music press and live sessions.
