At age 88, Tsuruko Yamazaki, one of the founding members of the Gutai group in 1954, now has a solo exhibition at Take Ninagawa in Tokyo featuring “a series of new works created on tin, her favorite medium due to its reflective and malleable qualities. Yamazaki uses dye, lacquer and thinner to create ethereal streaks and gradations of incandescent colors. Her work is on display through June 1, 2013.” Read more and see more of her artwork here.
