During a BARTER, the actors present their work to a specific milieu which, in return, pays with expressions from its own culture: songs, music and dances, biographical accounts, games, food samples, etc. During meetings with workshops, the participants are invited to take part in the Barter and show of samples of their own work.

A BARTER may take place in crowded urban districts or isolated rural zones, among immigrants, specific ethnic or religious minorities, in hospitals, community centres, prisons, schools, with the fire brigade, the police, a rock club, rappers, a church and its parishioners, the patients of a mental asylum, the children in a kindergarten, etc.

It is a social interaction that functions in spite of language barriers and cultural differences. A BARTER includes elements that are not necessarily artistic in themselves, but acquire a theatrical value and function, such as sports events, religious ceremonies, fish auctions, military exercises and manoeuvres.
