Longser is one of West Java traditional theatres in Indonesia that continues to grow and attract attention from the younger generation. The existence of Longser Festival started in 2007 and continues to this day with participants from the younger generation. This phenomenon is interesting, as the current young generation is mostly unfamiliar with Longser and is far from Sundanese, the regional language used in Longser. This research aims to investigate how the younger generation of festival participants prepares performance productions for the Longser Festival. The research was conducted by mapping theatre festivals held in Bandung with participants throughout West Java; and then observing the participants' performances from the perspective of mise en scène theatre at the crossroads of culture and cultural productions representing traditional arts with the younger generation in the circuit of culture. The participation of the younger generation in traditional theatre festivals contributes to reviving culture and tradition.
