Field notes
The library lists 35 equations, including the logistic map, Rule 30, the Collatz sequence, and the Lorenz-system expression shown as dx/dt=10(y-x). The page says AI composes each track and writes code that computes every sample, including voices and accordion; Naru Kijima then listens and selects what remains. Scores are presented in mathematical notation, and the album is linked through Spotify, Apple Music, Amazon Music, and other stores.
