Hans Zimmer's Remote Control

All over the world, there are unique and breathtaking sounds that you can only hear in one specific place. In this episode, we travel to two of the most astounding sonic wonders in the United States. The first is a hidden sound installation in Times Square that might be the most visited art exhibit on Earth. The second is an enormous organ built right into the rock of an ancient Virginian cave. These stories originally aired on the Atlas Obscura podcast.

Aural Obscura

If you listen to vintage music, one of the first things you’ll notice is the complete lack of bass. But turn on a Top 40 station today, and you’ll hear song after song with deep, sub-ratting bass tones. So how and why did this change happen? For this episode, we worked with OnePlus to tell the story of our collective obsession with bass, and the one device that transformed the sound of popular music. Featuring hip-hop legend DJ Jazzy Jeff and Roland's Paul McCabe.
