The improvisation classes held by A.Porfiriadis in the Music Department of Aristotle University of Thessaloniki during the years 2005-2009 was the basis for the foundation of 6daEXIt Improvisation Ensemble from him and a small number of students. Since its foundation in 2007, 6daEXIt is developed in one of the most important improvisation groups in Greece, with dozens of live performances and weekly meetings.

He was also a co-founder of Open Score Project. The group presented in concerts in Athens open form compositions that involved different levels of indeterminacy and/or improvisation (e.g. compositions by Earle Brown, John Cage, Karlheinz Stockhausen, Christian Wolff, George Brecht, James Saunders and Douglas Barrett). He was also member of the trio 'Seul a trois' together with Danae Stefanou and Natassa Mare Moumtzidou.

Porfiriadis collaborates with the austrian painter Manfred Url, as well as with improvisers active in Thessaloniki and in Athens.
