Last night I went to see a performance live "Doubtful guests Three acts of drawing and music" at cafe OTO. This was collaboration performance by 4 artists using prepared piano,percussion and ink drawing and tagtool. This was my first time to see tagtool drawing and I even could try using tagtool a little after the stage had finished. Me and my friends were really curious about this new tool for drawing. Especially I liked the colour projected on a wall very much.
