From 2014 to 2017 his workshop was part of the workshop program of the Nakas Conservatory Athens. The members of the 2014-16 class presented some of the most demanding verbal and graphic scores like Edges by Christian Wolff, But what about the noise by John Cage, Paragraph 6 from the Great Learning by Cornelius Cardew in a concert in Nakas Conservatory Athens.
