Matt Kwasniewski-Kelvin, co-founding guitarist of Black Midi, has died at the age of 26. His family confirmed his passing in a statement released via the band’s label, Rough Trade. Tragically, it was confirmed that his death followed a long battle with his mental health. Needless to say, this is a profound loss for the music community and for a generation shaped by Black Midi’s brief but consequential existence.
Kwasniewski-Kelvin’s openness and sonic extremity were integral to Black Midi’s formation and early identity.
Black Midi gained early attention through a series of uncompromising live performances around Brixton. These shows placed them at the center of the emerging South London scene alongside contemporaries such as Black Country New Road, and Shame. Emerging from that immediate circle, the band helped reshape modern post-punk and experimental rock, further expanding the genre’s boundaries with a singular vision.
Following the release of early singles on Speedy Wunderground, Black Midi signed with Rough Trade and issued their debut album, Schlagenheim, in 2019. The album received widespread critical acclaim and a Mercury Prize nomination, establishing the band as one of the most vital and challenging new acts of its time.
Kwasniewski-Kelvin’s contributions were foundational to the album’s restless intensity and uncompromising character.
After the COVID-19 pandemic, Black Midi returned with their second album, Cavalcade. However, Matt Kwasniewski-Kelvin was absent, having stepped away to focus on his mental health. At the time, he spoke openly about his condition, and in turn, the band offered their full support for his recovery. Unfortunately, he did not rejoin the group before their final release, Hellfire. Soon after that album’s arrival, Black Midi quietly ceased activity.
Outside of the band, Kwasniewski-Kelvin continued to make selective musical contributions, including guest appearances on Loggerhead by Wu-Lu. In 2024, he released a solo recording that reflected his political convictions and uncompromising approach to expression. In their statement, his family described him as a talented musician and a kind, loving person, and urged others to check in on those close to them in the hope of preventing similar tragedies.
Their message underscores the seriousness of mental illness and the importance of care, attention, and compassion.
Matt Kwasniewski-Kelvin’s career was brief, yet his impact was undeniable. Through his work with Black Midi, he helped shape a sound that challenged convention. In doing so, he pushed the boundaries of contemporary guitar music. As a result, his contributions will continue to resonate, and his absence will be deeply felt by listeners, peers, and the wider music community.
