Fontaines D.C. manager Trevor Dietz has died, the band confirmed in an official statement. The Irish group shared the news on Instagram, saying Dietz passed away on Sunday (June 7) and that they were “utterly heartbroken” by his death. No cause of death has been disclosed. He was 47.
“He was with us from the very start of our journey as a band, and we have never known Fontaines D.C. without him, the sixth member of the band,” they wrote. “He cared deeply about us and about fairness and justice in the wider world. He held strong, fearless beliefs. We will miss him forever.”
The band added, “We ask that everyone please respect our privacy and the privacy of his family during this incredibly difficult time. Rest in peace, Trev.”
Dietz was part of the band’s management team alongside Wildlife Entertainment, which has also worked with acts like Arctic Monkeys and Royal Blood. He had been involved with Fontaines D.C. since their earliest days and also worked as a promoter at Dublin venue The Workman’s Club.
During his time with the group, they released four studio albums: Dogrel (2019), A Hero’s Death (2020), Skinty Fia (2022), and Romance (2024). The latter earned a Grammy nomination, and the supporting tour included a headline show at London’s 40,000-capacity Finsbury Park. The band is also scheduled to return to live performances this summer with a headline set at Reading & Leeds Festival.
Dietz, who also ran the Garage Bar, began managing the band in 2016. In a 2019 appearance at the MIX (Music Industry Xplained) course, he spoke about meeting them for the first time. “I wouldn’t have worked with the band if they didn’t have massive ambitions and big dreams,” he said. “If other people had heard that conversation, they would have thought, ‘this is never going to happen’, but I knew we could take it far beyond Ireland. The key is working with a band that shares your vision and is reliable, accountable and honest.”
The group first released their debut single “Liberty Belle” in 2017 before signing with Partisan Records. Dietz also praised their creative confidence, saying, “They had the courage to express themselves lyrically and get their ideas across.” Fontaines D.C. later topped both the Irish and UK Official Albums Charts with Skinty Fia in 2022 and signed with XL Recordings in 2024.
In the same interview, Dietz reflected on his career, saying, “Getting through this industry for over twenty years without compromising.” He added, “I’ve never had to book an act I didn’t believe in.”
