The 23 bridges series contains references (clearly visible or hidden) to various artists, musicians or intellectuals in general. Some of them are: 

Malevich, Antonin Artaud, T.S. Eliot, André Masson, Gustav Dore, Luis Buñuel, The Velvet Underground, George Heimonas, Andrei Tarkovsky, Brancusi, Pasolini, Psychic tv, Demetrio Stratos.

Emphasis has been given to three of them: Antonin Artaud, G. Heimonas and Demetrio Stratos.
They share in common the exploration on the limits of language and a radical approach to life itself  - transformed by the passion that their revelations bring forth. 

The works that refer to each one of them, respectively are:

* Kré (no6)
Here appears a short Artaud's text, excerpt from "Pour en finir avec le jugement de dieu" along with a cd containing the legendary banned radio piece of 1947 which was broadcast only in 1973.

* Riot (no23) -both Heimonas and Stratos
The original work contains a Heimonas text in Greek. A translation of it will be given to the viewers in an A4 paper (to be translated soon). The text talks about the verbal and not verbal as well as art's function.
The second element of the work is a cd which contains the Greek child tongue-twister "O Tzitziras o Mitziras" as performed by Demetrio Stratos (source UbuWeb : Sound ).

Stratos says:
"If a new vocality can exist, it must be lived by all, and not singularly: an attempt to get freed by the condition of listener and spectator to which the culture and politics have accustomed us. This work does not be assumed as a passively listening, but as 'a game in which life is at risk' ".
