Teatro Praga  is a group or federation of artists with its own coat of arms and history. Given that every performance or day is something else, it usually answers the question of what it is by rephrasing the question. Even so, Teatro Praga rejoices with the established order and looks upon the unpredictable variations it subjects itself to as a way of broadening the notion of predictability. Teatro Praga was born in 1995 and is based in Rua das Gaivotas, Lisbon. It regularly collaborates with some of the most prestigious cultural institutions in Portugal and has performed in several European festivals and theatres (in Italy, the United Kingdom, Spain, Germany, France, Belgium, Hungary, Slovenia, Estonia, Denmark and Poland), as well as in Israel and China.

Metropolitana is a non-profit cultural institution established in March 1992 with the aim of promoting and teaching classical music. It manages two orchestras – the Orquestra Metropolitana de Lisboa and the Orquestra Académica Metropolitana – and three educational establishments – the National Academy of Advanced Orchestral Studies (higher education), the Metropolitana Conservatory of Music (primary and secondary levels) and the Metropolitan Professional School (integrated education).
