*300 copies limited edition* An electro-acoustic diary of the Fukushima family that records the "time and sound" exchanged between a parent and child in Niigata, using shakuhachi and a computer to respond. Reishu Fukushima began performing and improvising as a shakuhachi player after encountering the Muramatsu-style shakuhachi on Sado in the 1990s. His son, Satoshi Fukushima, explores the possibilities of interactive and unknown electronic acoustics with players through real-time computer processing. This work is the first "album" of the unit consisting of a father and son from Niigata. The physical shakuhachi performance, which shows deep breathing, is instantly responded to by being disassembled and processed using a computer, and the past is layered over the present in a progressive manner, creating a new, never-seen-before sonic image in a multi-layered manner. past and present, body and machine, decomposition and construction, betweenness and movement, composition and improvisation. The electro-acoustic layering is dignified and beautiful, moving between two contradictory events/phenomena, and eventually taking root at the border between them, like the blooming of glossy, soft petals. It is as if they are shining brightly into the future.
