Tibetan Achi Lhamo Dance 

Lhamo, or Ache Lhamo, is a classical secular theatre of Tibet with music and dance that has been performed for centuries, whose nearest western equivalent is opera. Performances have a narrative and simple dialogue interspersed with comedy and satire; characters wear colorful masks. The core stories of these theatrical plays are drawn mostly from ancient Indian Buddhist folk tales, lives of important people and historical events from Tibetan civilization. However the ceremonial, dance and ritual spectacles strongly reflects the Tibetan Royal Dynastic period.
Very similar traditions are found in Bhutan and other regions influenced by Tibetan Buddhism and Tibetan culture
