Steina and Woody Vasulkas are usually considered as the pioneers of the "electronic moving image". I will mention their balanced passion for "linking image and sound". They are also seen as "creators of new electronic instruments”. I will explain how they 'play' these instruments, the inherent 'performativity of their work' and will place their work in the context of history of "performative turn".
