This album is the 20th-anniversary of ATAK, the label established by Keiichiro Shibuya in 2002. It is a collection of music created for a live performance at Transmediale, a media art festival in Berlin, Germany, in 2008. Shibuya reconstructed and rearranged them thoroughly in 2022. It is also a milestone of collaboration with Takashi Ikegami, a researcher of complex systems and artificial life and a professor at the University of Tokyo. All sounds in the album consist of a multiplication of noise converted and generated internally by a computer from scientific data. It also contains quotes from a conversation in Berlin in 2008 with Otto E. Rösler, a German biochemist known for his work on chaos theory and the theoretical equation known as the Rössler attractor. In 2008, ATAK’s co-founder and Shibuya’s partner maria passed away. It was also the turning point in his music career – 2008 was the last year that Shibuya worked exclusively in electronic music before he began composing piano and opera music. In other words, it is a work that goes back to the roots of Shibuya’s music.
