Takatani Shiro was responsible for image supervision of "LIFE" (performed in Tokyo and Osaka), an opera by Sakamoto Ryuichi who tried to present an overview of music and society of the 20th century in 1999. In June 2005, a live performance,"Garden Series vol. 1: Experimental Live at Honen-in Zen Temple" in Kyoto, was conducted through laptops and images, fronting a garden of the Buddhist abbot's quarters. In June of the same year, Sakamoto and Takatani collaborated again in a Susan Sontag memorial live performance at Kyoto Zokei University. The images, in which Sontag's portraits and punctuation marks in her texts are arranged, are combined with sounds in a collage style, with various sounds dubbed onto "Spiegel im Spiegel" by Arvo Pärt. "LIFE--fluid, invisible, inaudible ..." was produced as a commissioned work at the Yamaguchi Center for Arts and Media (YCAM), and exhibited from March 10 to May 28 2007. On July 5 "Garden Series vol. 2", a live performance consisted of laptop-based sound and installation was held at in Daitokuji subtemple Yotokuin.
