Musicologist David Lewiston. Since the early 60s, Lewiston has traveled the world collecting the music of the indigenous cultures. He's recorded the Andean music of Peru, the fiestas of southern Mexico and the marimba music of Guatemala. In addition, he's travelled extensively in the Himalayas and other remote, mountainous areas of the Far East. These recordings have been released as part of the Nonesuch Record Company's Explorer Series. Over the last few years, Lewiston has focused on the music and rituals of the people of Tibet, now living in exile in northern India.
