Surface Impact Studies is, in this form, a performance of which I am co-author with Agostino Di Scipio.
He has elaborated several Surface Impact Studies (check xoomer.virgilio.it/adiscipi/ListOfWorks1.htm).
This particular form is for painting and electronics (adaptive live signal processing) commissioned by Champs d'Action, Antwerpen.
The video has an introductory text with a studio recording done in Di Scipio's studio, following is a 5 minute resume of the performance, it starts in sync to loose it after a minute or so. The audio of the performance is from the camera so it's just to give an idea of the physical gestures involved.
