In this episode of The Atlas Obscura Podcast, we visit the Luray Caverns in the Blue Ridge Mountains of Virginia, home to an instrument that draws out the secret sounds of millennia-old stone.

Our podcast is an audio guide to the world’s wondrous, awe-inspiring, strange places. In under 15 minutes, we’ll take you to an incredible site, and along the way you’ll meet some fascinating people and hear their stories. Join us daily, Monday through Thursday, to explore a new wonder with cofounder Dylan Thuras and a neighborhood of Atlas Obscura reporters.
