Well, the song "Dream Back to the Tang Dynasty" by the Tang Band is very atmospheric and antique. In addition, I recommend you to listen to Cheng Chi's Mahayana, which is pure music. Documentaries "Xuanzang's Journey to the West" and "Daming Palace" all use the music inside, which is magnificent, elegant and tragic. If you like the Tang Dynasty, I suggest you watch the documentary Daming Palace. Or look at the book "Night in the Tang Dynasty". There are three books, which are quite good. They describe the history of the Tang Dynasty from the side by solving puzzles such as Youyang Miscellanies.
