Keiichiro Shibuya

Musician. BA, Music Composition, Tokyo National University of Fine Arts and Music. Shibuya founded ATAK in 2002 and made it his base. As an electronica label, ATAK already has some CD releases of various artists: GOEM, Kim Cascone, stilluppsteypa, slipped disk, etc. Further, ATAK involves some experts from diverse fields such as space design, network technology, etc. He has presented many installations, in close corporation with the members of ATAK. In 2003, ATAK released "ATAK002 keiichiro shibuya + yuji takahashi". An active collaboration between Shibuya and Yuji Takahashi, composer/pianist, resulted in this piece. In this year, he also invited stilluppsteypa from Iceland and toured around Japan together(4 cities). In 2004, his first solo album "ATAK000 keiichiro shibuya" was released. And its outstanding quality of composition focused on sound texture and rhythm gained his reputation :"000 is definitely a great achievement. He has transformed the history of electronic music after the sine wave movement into his composition.' "
Now, He has multidisciplinary ongoing projects with some authorities such as Yuji Takahashi, Takashi Ikegami etc. Shibuya and Ikegami, who is an foremost expert on the area of complex systems, are undertaking the joint study called "The Third Term Music" and doing research on the music of variations and motion based on the theory of nonlinear physics. A symposium related to this project including a live performance was held at NTT InterCommunication Center°őICC°Ō(Tokyo, Japan) in December 2005. A sound installation "Description Instability" was exhibited at the same time. The third term music is a continuous project. From April 2006, He became an adjunct instructor at University of Tokyo.



Takashi Ikegami

Scholar. Taking PhD. in Physics from the university of Tokyo in 1989, Takashi Ikegami has been associate professor at the department of General Systems Studies, Graduate School of Arts and Sciences, University of Tokyo since 1994. His research theme is "Complex Systems = Understanding life systems based on computer simulations", and has been challenging the construction of life systems theory from dynamical systems perspectives. After taking PhD., he proposed a new theory of ecosystems based on °»homeo-chaotic°… dynamics collaborating with Kunihiko Kaneko. Chaos is often taken as a disgusting factor in ecosystems. But they showed that weak chaos of many degrees of freedom preserves diversity in an eco-system in a dynamic way. Since then he has been greatly contributing to the Artificial Life studies and has been working in different themes such as, self-reproduction, computational theory and evolutionary game theory. In particular, a model of machine-tape coevolution as a computational metaphor for the evolution of genetic code was well known. He studied an evolution of a set of virtual machines in a computer that read tapes and decode machines out of them. Two notions of noise, the machine origin and the external cause, were taken as two important factors that introduces evolvability of new machine-tape network constructions. This work was collaboration with Takashi Hashimoto. The machine-tape network theory is now used in the third term music composition, a joint art project with Keiichiro Shibuya.
Currently he has been more interested in the study of perception and consciousness from dynamic perspectives. He is a member of the EU project °»ECAgents°… and also serving as the editorial board of three international journals, Artificial Life, Biosystems and Interaction studies.
