Repetition, progression, and minimalist rhythms are the core of Supermercado, with melodic counterpoints coming together to form exhilarating sonic mosaics. The cult success of the album allowed Corridor to return to Europe, as well as make their first foray into the United States at SXSW 2018 with showcases for Brooklyn Vegan, Margin Walker, Felte/Part-time Punks, and M for Montreal.
Corridor also appeared at Northside Music Festival in Brooklyn that year, where they performed with the likes of Snail Mail, Deerhoof, and Protomartyr.
Shortly thereafter, they returned to the U.S. supporting U.K. post-punks Shame. In 2019, Corridor accompanied the band Crumb on a sold-out American tour. Then in May of 2019, they followed with performances at London Calling Festival in Amsterdam and La Villette Sonique Festival in Paris.
“The Montreal band Corridor knows how to highlight its strengths while getting in and out of a song with maximum efficiency: Sung in French, "Coup d'épée" only needs a little more than two minutes to let its robust guitar sound — a kind of weaponized jangle — fully worm its way in your head.” ["Coup d'épée" / Supermercado] - NPR Music
“Supermercado is the best French record of 2017, 2018, 2019, 2020, 2021, and even 2022 (for all we know, at least, since I doubt the Earth will explode exactly at midnight on January 1, 2022, even if it's a possibility we shouldn't ignore).” - Vice
Corridor will release their Sub Pop debut later this year.
