A January, 2026 Pitchfork article published after Matt Kwasniewski-Kelvin's passing detailed how he became an influential part of modern music history. Born in 1999 in London, England, Matt Kwasniewski-Kelvin went on to co-found Black Midi in 2017 with Geordie Greep, and Morgan Simpson, before Cameron Picton would soon join them.
