One cell. That's all it takes.

Rule 90 is a cellular automaton — a grid where each cell lives or dies based on its neighbors. Start with a single living cell and let Rule 90 run forward, and it builds the Sierpinski triangle: a fractal that contains copies of itself at every scale. The pattern grows from nothing into something that repeats its own shape forever.

The A-side is that growth. Ninety seconds, starting from near-silence. One frequency appears, then another, then layers begin accumulating. The piece doesn't build toward a climax — it builds toward complexity. The fractal filling in.

The B-side is the same thing in reverse. Full complexity collapsing back to a single cell. Dense sound dissolving into silence.

Same rule. Same seed. Opposite directions.

A-side — Emergence

Rule 90 | Seed 1 | Octatonic | 90s | forward

B-side — Dissolution

Rule 90 | Seed 1 | Octatonic | 90s | reversed


This is our fourth release. The first three used Rule 110 — a rule that generates irregular, unpredictable patterns. Rule 90 is different. It's deterministic and self-similar. The title is literal.
