Oliver Tree Nickell (Born June 29, 1993) is a vocalist, producer, and prolific scooter rider hailing from Santa Cruz, California. On March 27, 2016, Oliver released a video on Vine, entitled, “I’m Turbo”, which was the first appearance of his persona, Turbo.

He released music under the name Tree before “When I’m Down”, his upbeat dance song with collaborator Whethan went viral, leading him to sign with Atlantic Records in 2017.

The genre-defying Alien Boy EP, the world’s first glimpse at Oliver’s potential, followed the next year and earned tens of millions of streams. Known for his big-budget music videos and the comedic clips posted on his social media, Oliver joined The Chainsmokers on select dates of their tour and played many festivals while attracting attention to his unique and unorthodox fashion sense.

The Huffington Post described Oliver as “an enigma of genre. While (Oliver is) primarily a pianist, guitarist, and producer, his real-instruments-based-production incorporates rap, male and female vocal harmonies, poetic lyrics, strings and a hearty dose of synth…”

Oliver’s debut album, Ugly is Beautiful, released July 17th, to astonishing fanfare, reaching top 3 on the iTunes charts within 24 hours of it being released.

Oliver followed up the release of Ugly is Beautiful almost a year later with a Deluxe edition of the album that released on May 28th, 2021.
