Classical music maestro Gustavo Dudamel has spoken out against the Venezuelan government he has long performed for over its bloody crackdown on protesters.
Dudamel's statement followed the death of 17-year-old Armando Canizales during a demonstration on Wednesday.
Armando was reportedly a member of the government-financed El Sistema musical education programme that gave rise to Dudamel's career.
He has continued to work with it even while serving as the Los Angeles Philharmonic's musical director.
Critics have criticised Dudamel in the past for being cosy with President Nicolas Maduro.
But Dudamel called on Mr Maduro to reduce tensions and allow dissent in an essay posted on Facebook.
It bears Armando's name in a black, tombstone-like box.
He wrote: "It is time to listen to the people: Enough is enough."
