We provided the visual accompaniment for Anja Kaufmann‘s music in her performance on Friday 15 July at the Echofluxx Experimental Music and New Media Festival in Prague.In the photo above Dima is setting up our equipment in the main hall at Trafačka Gallery, an old power station building in Prague that has found a new life as artists’ studios. For this performance we used three projectors; the two that are visible in the photo covered the whole of the back wall and extended on to the side walls of the gallery and the third was positioned for back projection behind the translucent screen in the centre. Initially, Anja thought that she would perform behind this screen so that her silhouette could become part of my Tagtool drawing. However, in that position she could not see what I was drawing so instead she set up her laptop next to my Tagtool.In the photo below you can see the new (temporary!) modification that Dima made to my Tagtool specially for this performance. He extended the top of my Tagtool All-in-one so that I could have two Wacom tablets side by side, one to handle the drawing on the wall and the other the back projection on the screen – but best of all, with the one pen I could draw on either of the tablets or draw continuous lines from one to the other.Dima had video footage to project behind my drawing and for the performance he also put live video of Anja’s performance into the mix on the back projection. Needless to say this was all very complicated to set up and we had some very anxious moments before he got everything working…..I was too busy drawing to take any photos during the performance but Dima took video which I will put in a later posting.
