A podcast about hidden systems

The world runs on things nobody looks at.

Every Tuesday, Nadia Ferreira and Cole Wexler take one ordinary thing — sand, elevator music, a shipping container — and pull it apart until you can't unsee how it holds everything else together.

Your hosts

One reporter, one systems nerd. They disagree on roughly everything except the mixing levels.

Nadia Ferreira

Co-host · Reporting & tape

Twelve years producing overnight radio before she quit to chase field tape full-time. Nadia does the travel, the interviews, and the parts of the show recorded inside grain silos, container terminals, and one memorable municipal sewer.

Cole Wexler

Co-host · Research & scoring

Former freight logistics analyst who read one paper about sand mining and never recovered. Cole builds the research files, argues with the sources, and composes the show's score on a borrowed tape machine from 1978.
