The studio
Halo Field is a light-and-sound studio founded in Manchester in 2016. Pulse, their flagship touring installation, premiered in 2019 and has since played nine cities on three continents.

Since 2016
Started because a beautiful cue deserved a room that could hold it.
Wren Castellano spent six years as a lighting associate on arena tours, watching thoughtful design get compressed into a four-minute cue between headline acts. Idris Okafor was scoring documentary features and wondering why nobody built a room around a piece of music instead of the other way around. Pulse is the answer they built together: a show with no headliner, where the room itself is the reason to come.
Ten years later, Halo Field is nineteen people — lighting programmers, audio engineers, a mechanical engineer who keeps the kinetic rig alive on tour, and a production manager who has personally walked every venue Pulse has ever played.
