Sum and Substance is a Montreal-based band redefining modern math rock with raw intensity, technical prowess, and undeniable hooks. Instead of a traditional rhythm player, the group features co-lead guitarists Jeffrey Lehberg and Sehmim Al, who trade riffs and melodies beneath Alex Kofman's searing vocals.
Following the release of their latest single ''The Box,'' Sum and Substance hit the road for a mini-tour across Montreal and Ottawa, delivering 3 relentless performances that earned them spots on curated playlists such as RUN ROCK | RUNNING MOTIVATION 2025 and GYM BEAST ROCK.
With more new music on the horizon and shows booked alongside rising and established acts, Sum and Substance continue carving out their place in the next wave of sadboi anthems.
''With The Box, Sum and Substance proves they're a band to watch in the alternative scene. Their blend of math rock technicality and melodic accessibility makes them a refreshing presence.'' -Expansion Radial, 2025
