On 21 August we drove from Šumava to Plzeň where Vložte kočku were playing at the street music festival. The stage had a white tarpaulin roof and a light grey fine mesh rear ‘wall’ through which the contours of the building behind were dimly visible. I was able to draw over the whole stage and the roof – two different surfaces which produced some interesting effects, a lot of distortion in the drawing on the roof and slightly out of focus double images behind the band. I began by using black and white with quite a lot of transparency as opaque colours looked quite different on the two surfaces, the roof being much brighter.Dima took some photos from the side of the stage where the effect of the mesh background on the Tagtool drawing can be seen clearly….…and in this ‘behind the scenes shot’ the shadows of the musicians and their instruments produced a ghostly, almost surreal effect. Dima took a lot of photos at the concert – what follows is just a small selection.Here is a close-up shot to end this post. I have many more photos and also some pieces of video which I’ll try to post later – when I have some ‘free’ time!
