Oliver Tree, the eccentric singer known for viral hits like “Alien Boy” and “Life Goes On,” has died at the age of 32 following a helicopter crash in Rio de Janeiro.

Two helicopters collided over Rio de Janeiro on Sunday morning and crashed in the city’s western zone, killing all six people aboard, firefighters said.

Hours earlier, the singer updated his more than three and a half million Instagram followers with a video montage of a joyful day he spent playing football and exploring the country.
