Dumb are good at plenty of things, but relaxing isn’t one of them. The Vancouver four-piece write feverish tunes at a frantic pace, delivering their post-punk songs in two-minute blasts of wiry riffs and indignant social critiques. Less than a year since they signed to Mint Records for 2018’s Seeing Green, they’re already back with a new full-length, as Club Nites will be released on June 7.
