Hosts & story

Two microphones, one table, a lot of follow-up questions.

Overtone started as a running argument between a designer and a journalist about who really makes things. Sixty-two episodes later, neither of them has won.

How an episode gets made

About forty hours, for one hour.

  1. 01 · 20 hours

    Research

    We read everything the guest has published, call two people who know them and visit their workshop if we can.

  2. 02 · 3 hours

    Recording

    In person whenever possible, on dynamic microphones, with the phone in another room. No script, a page of questions.

  3. 03 · 17 hours

    Editing

    Rosa cuts three hours down to one, Kit scores it, and the guest hears it before anyone else does.
