Natalia Fentisova (1986) grew up in Russia and Finland. She graduated in art and media in the Berlin University of the Arts & Brera Academy in Milan. During her studies she exchanged for one year in California Institute of the Arts in the program of Film & Video. Her work includes film-essays, short films & audiovisual performances, where she explores psychological and physical transformations, questions of cultural, social and gender identities. Nowadays she manages blitzar media as a producer, director and film editor.

Sieva Diamantakos was born in 1980 in Rome and grew up in Liguria close to Genoa. He started filming while he was attending the university in Bologna and Amsterdam. After the graduation he moved to Genoa where he worked as cameraman for the ferry company ‘Costa Crociere’.

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 Diamantakos’ 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. He currently lives between Genoa, Kyiv and Berlin where he works on his second feature documentary.
