Tibetans are well represented in Chinese popular culture. Tibetan singers are particularly known for their strong vocal abilities, which many attribute to the high altitudes of the Tibetan Plateau. Tseten Dolma (才旦卓玛) rose to fame in the 1960s for her music-and-dance suite The Earth is Red. Kelsang Metok (格桑梅朵) is a popular singer who combines traditional Tibetan songs with elements of Chinese and Western pop. Purba Rgyal (Pubajia or 蒲巴甲) was the 2006 winner of Haonaner, the Chinese version of American Idol. In 2006, he starred in Sherwood Hu's Prince of the Himalayas, an adaptation of Shakespeare's Hamlet, set in ancient Tibet and featuring an all-Tibetan cast.
