We bring a live open-sourced attitude to electronic music. For us, music is code and hacking is performance. Source code is our instrument and we play it live.

Formed by Sam Aaron and Jonathan Graham, Meta-eX apply the arts of controllerism and live coding to weave immutable data structures into ephemeral sounds.
