Yasuo Sum - Gutai Group
«Yasuo Sumi was born in 1925 — 2015. After joining Gutai in 1955, Sumi becomes a member of Art Club, the group represented by Taro Okamoto...Plenty of his works have become property of public national museums all over the world. Sumi is today an active member of the AU Group and participates to the group exhibitions.He uses abaci, vibrators and combs for his works. While painting and performing Sumi always wears a pair of geta (woodden japanese shoes) and a bangasa (japanese umbrella), and uses a soroban (japanese abacus). But the use of these instruments is peculiar: sorobans are, for example, used, together with japanese ink to create straight and curved lines on papers and canvas. Bangasa is used to blow violently canvases, thus making them damaged. Vibrators are used to spread rhytmically colours on papers and canvases.»
