Shiraga studied painting in Kyoto and was a founder of the Zero Group and later became part of the Gutai Art Association (in the year the association disbanded). He originally specialized in Japanese painting but later moved into oil. The paintings shown here are oil works.
These pieces use paint liberally and powerfully. His technique includes dripping paint onto the canvas rather than using a brush.
Uemae studied Chinese painting before switching to oils and becoming an apprentice of Jutaro Kuroda. He then moved into abstract painting and was one of the founders of the Gutai Art Association. His work both makes use of pointillism and stitched works.
Among the museums with his work in their collections arel; the National Museum of Art (Osaka), the Les Abattoirs museum of modern and contemporary art (Toulouse), and the Pompidou Center (Paris).
