Oliver Tree, the California-born singer-songwriter known for tracks like “Life Goes On,” “When I’m Down” and “Miss You,” died in a helicopter crash in Rio de Janeiro, according to CNN Brazil.

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.

Once Tree dropped “Life Goes On,” he never looked back, with the track becoming platinum in under two years, only to be surpassed by “Miss You” going 2x platinum in five countries shortly afterwards.
