Show Notes

All podcasts, regardless of their format, are a creative endeavor. But some podcasts are just more complex. Enter, Bellwether, the latest offering from award winning podcast and radio producer, Sam Greenspan.

Sam is the founding producer of 99 Percent Invisible and has a number of impressive credits to their name. The City from USA Today, the TED Radio Hour at NPR and Radiotopia’s Spacebridge to name a few. They’ve also lectured and taught radio and podcasting around the world. In November of 2021, Sam was hired as a Senior Producer at Vice Audio.

So when Bellwether was released, the podcasting world took notice. Bellwether was a five year effort from one of the most brilliant minds in podcasting. This five episode narrative weaves together both real world reporting (stories Sam personally covered) and a fictitious Sci-Fi story arc. Described by Sam as a “new podcast of speculative journalism” Bellwether examines what the world is through the lens of what it might become.

Flash Forward: Ethically Mixing Fact and Fiction (ft. Rose Eveleth)

In 2021, we’re blessed to live in a podcast landscape ripe with richly reported nonfiction shows that challenge your way of thinking and expand your world: Reply All, Invisibilia, Far Flung, the list goes on. There is also an expanding slate of fictional podcasts to get lost in. But what if you could have both in one show?  With Flash Forward, a show about the future, our guest Rose Eveleth inspires imaginations and pushes listeners to think about the world we live in now, and how it could be different. Like other science shows, Rose calls on scientists and other experts to break down complex concepts in an accessible way. But sprinkled throughout each episode are speculative fiction scenes that offer a glimpse of “possible and not so possible futures.”  In this episode of 3 Clips, Rose and Jay break down a Flash Forward episode about humans’ search for alien life. They discuss how to make scientists sound podcast-worthy, how Rose has carved out her own voice in the science genre, and her fiction writing process. Also, Rose offers insights on how she’s managed to make such a multilayered show as an independent producer.  EXPLORE THE SHOW for all episodes of the show.  LEARN MORE ABOUT 3 CLIPS HOST JAY ACUNZO Subscribe to his newsletter, explore his course for podcasters, or watch and listen to all of Jay’s shows and projects at  LEARN MORE ABOUT CASTOS 3 Clips is a Castos Original Series.
