With every release, the music of Toronto duo Northumbria pushes further outward. The scale of their panorama increases, manipulating the tones of guitar and bass in a manner that not only considers breadth, but also mimics the undulation and fracture of natural landscape. Drones intersect to form glacier tips. Harmonies microtonally melt into the sea. The band are currently working on a trilogy of releases focused on the Norse discovery of Canada over a thousand years ago; the second of these releases, titled Markland, came out on Cryo Chamber back in March this year. Below, Northumbria and I discuss tuning the room, strict minimalism, and the band’s technological evolution.
