No wonder they’re called Ought. The Montreal art-punk band cohered during the city’s 2012 student strikes, and its stirring debut album,More Than Any Other Day, meditates on one broad theme: There are things—our lives, our laws, our societies—that are profoundly wrong, and they ought not be. Lots of critics have compared the group to Talking Heads, and it’s true that some songs share the combustible tension of Talking Heads: 77 and More Songs About Buildings and Food. But Ought has just as much to do with modern DIY standard-bearers like Titus Andronicus and aural abusers like Sonic Youth.
