In 1998, Sandy Tolan, an American journalist and author, met Ramzi Aburedwan, a 19-year-old Palestinian musician living at the time with his impoverished grandparents in a refugee camp near Ramallah on the West Bank. That meeting led to a piece on National Public Radio about the young musician with a dream of a career in music and “Children of the Stone: The Power of Music in a Hard Land,” Mr. Tolan’s 2015 book about Mr. Aburedwan and the broader social and cultural context in which his story has unfolded.
