The Drepung Monks started Sunday morning of the festival with the sacred music of Tibetan temple music. The multiphonic singing is called jok-kay (low tone) and bar-da (high tone). They have been featured on the soundtrack of Seven Years in Tibet. They have also performed with Paul Simon, Sheryl Crow and Michael Stipe, just to name a few. An outstanding performance. They also were kind enough to lead a guided meditation later that evening.
