Takeda Shinpei was invited to create an art installation at Centro Nacional de las Artes, located in Mexico City. This chapter is a vivid telling of Takeda's process working on this piece, part of his Alpha Decay series which foregrounds voice vibrations of survivors of the U.S. atomic bombings. Takeda details the ways in which he drew from his own memories of adolescence, reckoned with voices of the “hibakusha,” and channeled these complex and haunting intersections through his body into his art. Takeda thus weaves a powerful yet honest and vulnerable narrative that shares reflections on method and ethical praxis.
