Radiolab collaborated with Detour to make an interactive audio tour. It’s like walking around inside a Radiolab episode. And you can only do it in Austin.

This is a brand-new experiment for us, and we want feedback from our listeners in Austin (if you like it, we might make more for other cities!). If you’re at SXSW, it’s a perfect escape from the craziness of the festival. And if you’re an Austin native, it’s a chance to see your city in a whole new way.

On the Detour, you’ll investigate a 130-year old murder case. You’ll get the smell of 1885 in your nostrils, the songs of Shakey Graves in your ears, and—if you’re in the mood—the taste of tequila on your tongue. You’ll pass through cool little shops, down into a creek bed, and through a hidden labyrinth.

All you need is an iPhone, a pair of ear buds, and a willingness to try something new.

Get Detour from the App Store. In the Detour app, download “Radiolab Presents: The Year That Broke Austin.” Make sure your phone battery is charged—then head to the starting location in downtown Austin, press play, and enjoy.
