Over the past 20 years, Canadian anarcho-punk band Propagandhi has evolved more than most of its peers. It still plays at blistering speeds and espouses lefty politics and veganism, but its melodic skate-punk has been replaced by complicated metal-leaning songs and structures, as evidenced by the addition of a second guitarist and 2012’s Failed States, 37 minutes of sheer face-pummeling bliss. With Flatliners, War on Women. Neumos. 7 p.m. $18. DAVE LAKE
