American musician Oliver Tree, 32, died Sunday after two helicopters collided near Rio de Janeiro. The crash killed six people in total; five occupants were in one helicopter and only the pilot was in the other, PolíCIA Civil confirmed. Authorities said Tree appeared on the passenger list handed to aviation investigators but officials have not yet identified the bodies. Tree was a high-profile alternative-pop artist known for theatrical videos and international touring, including a recent São Paulo show, so his death affects ongoing concerts and promotions.
