At its core, “Strangers” is a profile of renowned cellist Yo-Yo Ma, a symbol of “world music” before the term was even coined. We see a clip of a young Ma introduced on a television special by conductor Leonard Bernstein as a Chinese musician playing French music for American audiences.

The camera pulls away to reveal that the audience that day included President John F. Kennedy and first lady Jacqueline Kennedy.

A clear prodigy, Ma admits he never felt a clear passion for Western classical music.

He was simply a great player at a very early age.

He spent much of his youth and middle age searching for his musical voice, a search that brought him to create the Silk Road Ensemble in 1998.

The rotating group of musicians blends new music out of instruments familiar and obscure. “Strangers” puts the spotlight on the stories of Kinan Azmeh, a Syrian clarinet player and composer; Wu Man, a pipa player and composer from China; Kayhan Kalhor, an Iranian kamancheh player and composer; and Cristina Pato, a bagpiper, pianist and composer from Spain.

Each tells stories filled with tragic history. Wu Man championed a form of traditional Chinese music all but stamped out by the Cultural Revolution.

Kalhor was driven from his home after the Iranian Revolution of 1979, despite the fact that he was striving to keep traditional Persian music alive.

Azmeh has watched his beloved Syria reduced to rubble.

All the musicians involved in “Strangers” have been criticized for abandoning their traditions to create an artificial hybrid music for trendy audiences.

Yet each of these musicians has used the ensemble to champion and preserve ancient sounds.

At a time when societies around the world are wrestling with nationalist movements that see global cooperation as a threat to their culture and heritage, “The Music of Strangers” could not be more timely. And the music will blow you away.
