Dumb were founded in Vancouver, British Columbia, by guitarist and singer Franco Rossino, guitarist Nick Short, bassist Shelby Vredik, and drummer Pipé Morelli. Dumb were playing regularly in Vancouver not long after they launched in 2015, and a few months later they issued a self-released EP, Friendship. After the release of Friendship, bassist Vredik dropped out of the group to pursue other interests, and Brett Barmby joined the band in time for its second EP of 2015, Tulips. Barmby left Dumb to attend grad school, and Gavin Ray (Franco's brother) took over as bassist for the recording of the nine-song Beach Church, an experiment in surf music influences that was released in February 2016.
The group wasted little time going back into the studio, and Mustang Law, an album that found Dumb back in arty punk territory, came out in October 2016. After the album was released, Ray left the group to go back to college ("Grad school kept stealing our bassists," Rossino told journalist Judah Schulte) and Shelby Vredik returned to Vancouver and rejoined Dumb. With the original quartet back in action, Dumb rounded out 2016 with the December release of the six-song Dumb EP 5$ or Free. As Dumb settled back into a familiar lineup, they devoted 2017 to live work, playing often in Vancouver and staging three concert tours. In April 2018, Mint Records, among Canada's most respected independent labels, revealed that Dumb had signed with them, and two months later, the band released their next album. Titled Seeing Green, the album featured some of Dumb's strongest work to date, with the title nodding to the themes of money, envy, and inexperience. June 2019 brought a second Dumb album via Mint, Club Nites, a similarly fierce set that the group described as "a collection of narratives drawn from the nightlife ecosystem." ~ Mark Deming
