I'm Will Daly. For years I've been on the road playing shows and seeing America through live music.

This summer I'll hit the stage with Season 2 of Sound of Artown.

Ten cities, 12 episodes, every other Thursday.

We explore the live music venues and culture of a new American city with each new episode.

Our tour continues into the kind of venues you want to get to when you land in Detroit.

Providence, Denver, or Seattle.

Listen to Sound of Artown on the I Heart Radio app, Apple Podcasts, or wherever you get your podcasts.

It's an early February morning on the banks of the Zherwa River in Brazil.

Not far from the Peruvian border.

I'm with Louisa Abram and her dad, Andre.

And we're here on a simple mission, really.

Just try and save the most fragrant chocolate on Earth from total extinction.

We just arrived last night after a full day of travel by planes and small boat.

And after a rough night in a basic hut, we're moving a little slow as we take stock of the situation.

The story of this mission goes back a few years.

Louisa had just dialed in her technique for producing great chocolate from wild cacao beans.

When a nonprofit called SOS Amazonia that works to protect the Amazon its people, came to her with a plea.

They had just found cacao growing along the banks of the Zherwa River in a pristine area where the people had almost no source of income.

Which she considered working with them.
