Black Midi Co-Founder Matt Kwasniewski-Kelvin Dies at 26

His family said he died after a long battle with his mental health.

Overview

  • The announcement was shared via a family statement posted by Rough Trade Records, which also directed people to mental-health support resources.
  • Kwasniewski-Kelvin co-founded Black Midi after meeting bandmates at the BRIT School and helped shape the group’s early sound in Brixton’s Windmill scene.
  • He performed on the 2019 debut album Schlagenheim, which earned a Mercury Prize nomination and established the band’s reputation.
  • He stepped away in 2021 citing being mentally unwell and did not appear on the subsequent albums Cavalcade and Hellfire, though he retained some songwriting credits.
