See a Khon Theater Performance#18 of 43 things to do in Bangkok
If you think of yourself as a theatergoer, make sure to pop into the National Theater of Thailand, for that’s where all khon or lakhon (its contemporary variation) classical performances in the Thai language are held. Not knowing a word of Thai is, of course, a disadvantage as the plot will be beyond you, but the rich setting and ornate traditional costumes of the cast will compensate it.
Instead of a theater performance, you can actually end up at a concert. They have a live music venue there.
