Thailand's entertainment culture is built around a performing arts tradition of extraordinary visual complexity. The Khon masked drama — a classical Thai theatrical form depicting scenes from the Ramakien (the Thai Ramayana) through elaborate golden costume, precise gesture vocabulary, and instrumental accompaniment — is UNESCO-listed and performed at the National Theatre and the Chalermkrung Royal Theatre in Bangkok. The Phi Ta Khon ghost festival in Dan Sai, where participants wear painted ghost masks and process through a small northern town in a celebration that mixes Buddhist ceremony with ancient spirit worship, is one of Asia's most visually extraordinary festival entertainments. Muay Thai boxing matches, with their pre-fight wai kru ceremony and live pi-phat musical accompaniment, are as much performance as sport. The Thailand Philharmonic Orchestra and Bangkok's booming club music scene add classical and contemporary registers.
