Fontaines D.C. Mourns Death of Longtime Manager Trevor Dietz

Fontaines D.C.’ s manager Trevor Dietz has died, the band confirmed in a statement. The Irish five-piece confirmed via Instagram that Dietz passed away on Sunday (June 7) and said they were “utterly heartbroken” by the news. A cause of death has not been made public.

“Trevor was beside us from the beginning of our journey as a band, we have never known Fontaines D.C. without him, the sixth member of the band,” the band wrote. “He cared passionately for us and for what was fair and right in the wider world. He was fearless in his beliefs. We will miss him always.”

Fontaines D.C. added, “We ask that you kindly respect our privacy and that of his family at this terribly difficult time. RIP Trev.”

Dietz formed part of the band’s management team alongside members of Wildlife Entertainment (Arctic Monkeys, Royal Blood). He had worked with the group in its earliest iterations, and also acted as a promoter for the Dublin venue The Workman’s Club.

During his time with the band, Fontaines D.C. released four studio albums: Dogrel (2019), A Hero’s Death (2020), Skinty Fia (2022) and Romance (2024). The latter was nominated for a Grammy at the 2025 awards, and the Romance tour saw the group headline London’s 40,000-capacity Finsbury Park. Fontaines D.C. is due to return to the stage this summer with a headline set at Reading & Leeds Festival.

Dietz, who also ran the Garage Bar, began managing the band in 2016. Speaking in at the MIX (Music Industry Xplained) Course in 2019, Dietz recalled their first meeting. “I wouldn’t have worked with the band if they hadn’t had huge expectations and huge dreams,” he said. “If other people had heard the conversation that day they would have gone, ‘Jesus, these guys are nuts, it’s not going to happen’, but I knew we could go well beyond Ireland with this. So, first and foremost, you need a band that shares your vision and who are reliable, accountable and honest.”

The group released its debut single, “Liberty Belle,” in 2017 and subsequently signed to Partisan Records. “They had the confidence to expose themselves lyrically and get their ideas out,” Dietz said in 2019. “As a manager, you want to know that a band are capable of doing things for themselves.” Fontaines D.C.’s 2022 album, Skinty Fia , hit No. 1 on both the Irish and the U.K.’s Official Albums Charts; in 2024, the band signed with XL Records.

Speaking in the same interview, Dietz reflected on his career highlights. “Surviving through this game for the past twenty years without having to compromise,” he said. “I’ve never had to put a DJ or a band on that I thought was s–t.”
