The most personal film script of the Mauthausen camp survivor and founder of the modern Greek post-war theatre Iakovos Kambanellis (Stella, The Ogre of Athens, Girls in the Sun) takes its final form, in the place where the martyrdom was experienced and the original inspiration came from. Kambanellis's Travelogue to Mauthausen-May 1988, was written during his visit and concert on Mauthausen Liberation and Commemoration Ceremony 1988, coming now to life on Mauthausen Liberation and Commemoration Day 2022 in its natural place -Mauthausen Memorial, Austria- for the first time. A poetic documentary and a unique musical, presenting the swansong Mauthausen Cantata new interpretation by Aristarchos Papadaniel (voice) and Aris Zervas (cello), published with the permission of the world-renowned Greek composer and political activist Mikis Theodorakis (Zorba, Z, Serpico) just one month before his passing.
