Everyone’s favorite polka-dotted microtonal duo Angine de Poitrine stopped by The Tonight Show With Jimmy Fallon on Monday night to make their U.S. television debut. (True devotees know they first graced the small screen on Later…With Jools Holland in June.) The Canadian math-punkers marked the occasion with a brand new song, “Zugzek.” Although Fallon struggled to pronounce the title, guitarist-bassist Khn and drummer Klek had no trouble ripping through the mind-melding five-minute track. Watch their performance below.

A self-described “Mantra-Rock Dada Pythagorean-Cubist Orchestra,” Angine de Poitrine shared their latest album, Vol. II, in April. They also played Newport Jazz Festival this summer, and recently brought a two-night run to New York’s Le Poisson Rouge.
