In China, Echoes of the Past – John M. Glionna

From Los Angeles Times:

Video recorder in hand, Wang Hong sat inside a small stone-and-brick house with one of China’s aging musical masters ” a Mongolian vocalist named Hajab who once sang his region’s ancestral melodies for Chairman Mao Tse-tung.

Wang had ventured from his home in San Francisco to the grasslands of Inner Mongolia on a quest to mine the ancient harmonies of the Middle Kingdom. He had lobbied state authorities and waited months for permission to visit Hajab.
