A new symphonic work by Cambodian filmmaker Rithy Panh and composer Him Sophy that will be performed in New York, Boston, and Australia was unveiled in Phnom Penh.

“Bangsokol: A Requiem for Cambodia” combines music, voice, movement, and visuals.

At a press conference announcing the piece, U.S. Embassy Chargé d’affaires Julie Chung said the composition “is a memorial to the tragedies of the 1970s Khmer Rouge period. But more importantly, it is about hope and continuance.”
