He was 1000% himself and on a mission to add more joy
On a Sunday morning over Rio de Janeiro, two helicopters collided in the sky, and among the six lives lost was Oliver Tree, a 32-year-old American musician who had built something rare — an audience that followed him not for a persona, but for the unguarded fact of who he was. He was in the middle of a world tour, his next stop weeks away, when the collision ended what had only just begun. The investigation into the cause continues, but the human cost is already fixed: six people gone, and with them, whatever they would have made next.
- Two helicopters collided over Rio de Janeiro on Sunday morning, sending one aircraft crashing into a car dealership lot and igniting roughly twenty vehicles in a chain of fire.
- Among the six killed were Oliver Tree, 32, a viral alt-pop musician mid-way through a world tour, and Argentine content creator Gaspar Prim Diaz — lives from different worlds, ended in the same moment.
- The music community responded with visible shock, with collaborators like KSI, Diplo, and Steve-O posting tributes that carried the particular weight of loss that arrives without warning.
- Brazilian authorities have opened an investigation into what caused the two aircraft to meet in the air, but no cause has yet been established.
- Tree's upcoming tour dates — Lisbon, Glasgow, Manchester, London — now stand as a quiet record of what was supposed to come next.
On Sunday morning over Rio de Janeiro, two helicopters collided in the sky. One fell onto the parking lot of a car dealership, igniting roughly twenty vehicles. Among the six people killed was Oliver Tree, the 32-year-old American musician born Oliver Tree Nickell in Santa Cruz, California, who had built a devoted following through viral songs like Life Goes On, Miss You, and Alien Boy — music that found its audience online before anywhere else.
Tree was in the middle of a world tour when the crash occurred. His last show had been in São Paulo on June 6th; he was due in Lisbon on July 1st, then Glasgow, Manchester, and London in September. Also killed were Argentine content creator Gaspar Prim Diaz, passengers Lucas Brito Chaves and Lucas Vignale, and the pilots of both aircraft. Brazilian authorities have opened an investigation into the cause.
The tributes that followed painted a consistent picture. KSI, who had collaborated with Tree on the track Voices, wrote that he should still be here, that he had so much music left to make. Diplo said he didn't think the world would see another person quite like him — someone operating with no rules and no apologies, fully committed to adding joy to the scene. Steve-O remembered him as someone who checked in, who cared. Bebe Rexha called him passionate and kind. Kid Cudi called him a really amazing and beautiful human.
What the tributes share is a sense that Tree had moved through the world with a particular insistence on being exactly himself — not performing a version, but inhabiting the real one completely. He had built something genuine from that stance. The tour will not continue. The investigation goes on. The loss does not change.
On Sunday morning over Rio de Janeiro, two helicopters collided in the sky. One fell directly onto the parking lot of a car dealership, igniting roughly twenty vehicles in a chain of fire and smoke. Among the six people killed was Oliver Tree, the 32-year-old American musician and internet personality who had built a devoted following through viral moments and a sound that sat somewhere between alt-pop and internet culture itself.
Tree, born Oliver Tree Nickell in Santa Cruz, California, had become known for his distinctive bowl haircut and a string of songs—Life Goes On, Miss You, Alien Boy—that found their audience online before anywhere else. He had been nominated for a Brit Award in 2024 for Miss You, a collaboration with German producer Robin Schulz. Beyond music, he held a Guinness world record for constructing the world's largest kick scooter, a project that captured something essential about him: the willingness to pursue an idea fully, without irony or restraint.
He was in the middle of a world tour when the crash occurred. His last performance had been in São Paulo on June 6th. He was scheduled to play Lisbon on July 1st, then move through Glasgow, Manchester, and London in September. The tour was just beginning to unfold.
The other passengers included Argentine content creator Gaspar Prim Diaz, known online as Gaspi, along with Lucas Brito Chaves and Lucas Vignale. The pilot of Tree's helicopter was Alexandre Souza. The second aircraft carried only its pilot, Charles Marsillac. The Military Fire Department of Rio de Janeiro arrived at the scene around 9 a.m. local time. Brazilian authorities have opened an investigation into what caused the two helicopters to meet in the air.
The news moved quickly through the music world and beyond. KSI, the British YouTuber and Got Talent judge who had collaborated with Tree on the track Voices, posted a tribute that carried the weight of sudden loss. "Can't believe I'm actually having to type this," he wrote. "You're 32 man. You should still be here. You still had so much life to live. So much music to make." Steve-O from Jackass remembered Tree as someone who checked in regularly, who cared about how others were doing. "Such a great person," he wrote. "I'm going to miss him."
Other artists moved to honor him online. Diplo, who had worked with Tree on Ultraman for a Netflix superhero film, posted that he didn't think the world would see another person quite like him. "No rules. No apologies," Diplo wrote. "He was 1000% himself and on a mission to add more joy to this music scene." T-Pain thanked him for sharing his art and for always being different. Bebe Rexha called him passionate, talented, and kind. Kid Cudi hailed him as a really amazing and beautiful human.
What emerges from these tributes is a portrait of someone who had moved through the world with a particular kind of intensity—not performing a version of himself, but insisting on being exactly who he was, completely, without apology. He had built something real from that stance, an audience that understood him not as a product but as a person. The tour that was just beginning will not continue. The songs he had yet to write will not be written. The investigation into the collision continues, but the fact of the loss does not change.

The Hearth Conversation Another angle on the story
What was it about Oliver Tree that made him matter to people?
He didn't perform a version of himself. He was completely, unapologetically himself—the bowl haircut, the weird projects like the giant kick scooter, the music that lived online first. People responded to that authenticity.
So this wasn't a traditional pop star?
Not at all. He came up through social media, through going viral. He was an internet person who made music, not a musician who used the internet. That's a different thing entirely.
The tributes mention him checking in on people, caring about them. Was that part of his public persona?
It seems to have been genuine. Steve-O said he'd reach out regularly. These weren't obligatory statements—they were people describing someone who actually showed up for his friends.
He was only 32. The tour had just started.
Three days into it, essentially. He'd played São Paulo on June 6th. Lisbon was scheduled for July 1st. He was at the beginning of something.
What happens to the music he didn't finish?
That's the question no one can answer yet. The songs exist somewhere in his mind, in his notes, maybe in early recordings. But they won't be completed the way he would have completed them.
Do we know what caused the collision?
Not yet. The investigation is just beginning. Two helicopters met in the sky over Rio de Janeiro on a Sunday morning, and no one knows why.
