The last post on Oliver Tree’s Instagram showed him playing football in a sunlit Brazilian neighborhood. It was June 13. He had just performed in São Paulo days earlier, was midway through his “World’s First World Tour,” and was scheduled to continue to Lisbon on July 1.
The following morning, he was dead.
At 8:59 a.m. Brasília time on Sunday, June 14, two helicopters collided mid-air over Recreio dos Bandeirantes in Rio de Janeiro’s western zone. One aircraft, a Bell 206B JetRanger III registered PP-MAC, struck a second helicopter, a Eurocopter AS350 B2 registered PR-DJJ.
All six people aboard both aircraft were killed.
The Bell 206 crashed onto the grounds of a BYD car dealership, where the impact triggered a fire that engulfed multiple vehicles before firefighters brought it under control. Authorities said debris was scattered across the site, with parts of the wreckage landing within a wide radius of the impact zone.
Fire officials said the crash occurred in a densely populated area along Avenida das Américas, raising concerns about what could have happened had the aircraft fallen into nearby residential blocks.
Brazil’s Military Fire Department and civil aviation authorities confirmed both helicopters departed separately before the collision. The Bell 206 took off from Angra dos Reis, while the AS350 departed Jacarepaguá.
Investigators from Brazil’s National Civil Aviation Agency (ANAC) and the Air Force’s Aeronautical Accidents Investigation and Prevention Center are leading the probe.
Officials said human error has not been ruled out. Flight coordination, air traffic control procedures, and operational conditions are all under review.
Authorities also noted that the ownership and maintenance history of one of the aircraft is part of the broader investigation, including prior regulatory penalties involving the operator, which will be assessed as part of standard safety checks.
No cause has been determined. Technical analysis is expected to take weeks.
Oliver Tree Nickell was born June 29, 1993, in Santa Cruz, California.
His death was confirmed to his family through contacts in Brazil connected to the tour. His father issued a brief statement: “Peace be with Oliver. The family has no comments.”
Tree built a career defined by internet-era performance and stylized absurdism. Raised in Santa Cruz, he began music training early and later transitioned from scooter competition circuits into entertainment, using viral content and performance art as his entry point into mainstream music culture.
He studied music technology at CalArts, graduating in 2016, and gained early attention through collaborations and viral performances before signing with Atlantic Records in 2017.
His breakthrough came with a string of releases that included “Alien Boy,” “Hurt,” “Miracle Man,” “Life Goes On,” and “Miss You,” which expanded his audience internationally. His 2022 album “Cowboy Tears” charted on Billboard’s Alternative rankings.
His most recent project, released in 2026, supported a global tour spanning more than 70 shows across 30 countries.
Tree became known for a highly constructed public persona, marked by visual exaggeration, satire, and self-directed performance work. Industry collaborators often described him as precise and deeply involved in creative direction behind his videos and stage design.
He had performed in Buenos Aires on June 4 and São Paulo on June 6. Additional European dates were scheduled for the weeks ahead.
Tributes quickly spread across the music and entertainment industries. Artists and collaborators including KSI, T-Pain, Robin Schulz, Bebe Rexha, Kid Cudi, Diplo, and others posted messages mourning Tree’s death and reflecting on his influence on internet culture and alternative pop.
At a live show in Toronto, Post Malone acknowledged the news during his set, dedicating a moment of silence to Tree.
The tour he was headlining, which had more than 70 scheduled performances worldwide, has been halted.
Authorities said the investigation remains ongoing, with full technical analysis of both aircraft and communications records expected in the coming weeks.
Oliver Tree Nickell is survived by his family. He was 32.
