Concept, production, post-production


Natalia Fentisova grew up in Russia and Finland. She studied art and media in the Berlin University of the Arts & Brera Academy in Milan, exchanging for one year in California Institute of the Arts. She works as a producer and director. Her work includes documentaries, film-essays, shorts & cross-media projects, where she explores questions of psychological and physical transformations, cultural, social and gender identities.

Sieva Diamantakos was born in 1980 in Rome and grew up in Liguria, Italy. He started filming while he was attending the university in Bologna and Amsterdam. Later he became a member of port-royal, an emotional electronic band that inspired his fantasy. He developed a poetical visual language which was an inseparable part of the port-royal audiovisual show. For seven years he toured with the band all around the world, especially in the Eastern European countries as Russia, Ukraine, Serbia etc. Despite this intense collaboration, Sieva deepened his skills in many branches (commercial and independent) as director, cameraman, editor and VJ. Having developed a strong interest for the Eastern countries he decides to move to Kiev. There he worked on a documentary “Postcards from Ukraine” that depicts the political and social crisis in Ukraine.

Sieva’s work is deeply influenced by philosophy (mainly existentialism), sociology and the interaction between human and technology. His style of filming consists of both a visionary and emotional approach.
