YouTuber KSI has paid an emotional tribute to US singer and "legend" Oliver Tree, who is believed to have died after two helicopters collided in Rio de Janeiro. The American singer-songwriter, who collaborated with KSI on the song Voices and is known for the track Miss You, was listed as being on board a helicopter that crashed over the Brazilian city on Sunday morning, according to the Associated Press.
Details of the Crash
He was one of six people killed when the two helicopters collided over Rio de Janeiro and crashed in the city's western zone, firefighters said. Rio de Janeiro's Military Fire Department reported that one of the helicopters crashed onto a car dealership where several electric vehicles were parked, igniting a fire that was extinguished. Tree was on the passenger list handed to aviation authorities, police confirmed, but they have not yet identified the bodies of those killed in the crash.
KSI's Tribute
In a post shared on X, KSI said: "Can't believe I'm actually having to type this. You're 32 man. You should still be here. You still had so much life to live. So much music to make. So much content to make. You're a legend and will always be a legend. Still doesn't feel real. Genuinely feel sick. I love you bro."
Oliver Tree's Career and Tour
The 32-year-old was only weeks into his World's First World Tour, where he planned to play shows on all seven continents. He performed in Buenos Aires, Argentina on June 4, and on Saturday shared a video on Instagram playing football in a Brazilian neighbourhood. Tree was due to play more than 70 shows across 30 countries, including the UK, with dates scheduled in Glasgow, Manchester, and London in September. In 2024, he was nominated for the international song Brit award alongside German producer Robin Schulz for their song Miss You, which peaked at number three in the UK singles chart.
Guinness World Record
In 2020, Tree broke the Guinness world record for the largest kick scooter, measuring 0.16m tall and 3.13m long. According to its website, the record was broken to "fulfil a lifelong dream."
Investigation
Officials said an investigation is under way to determine the cause of the collision.
