Carsten Nicolai is one of the most renowned artists working at the intersection of art and science and infamous for his minimalist approach. Having exhibited internationally at Documenta X and the Venice Biennale, he is also an active musician working under his music alias Alva Noto and has staged performances with Ryuichi Sakamoto at the Guggenheim NY to the Centre Pompidou in Paris. This week, Gestalten is releasing his new book Grid Index, the first comprehensive visual lexicon of patterns and grid systems. A reference book for designers, visual artists, architects, researchers, musicians and mathematicians, Nicolai has discovered and unlocked the visual code for visual systems into a systematic equation of grids and patterns. We met Carsten in his studio in Berlin Mitte to talk about grids, books and music.
