The Arcs is a new project from Dan Auerbach of The Black Keys. He started the band with some of the musicians and producers he's worked with over the years. For this episode, Dan and his bandmates Richard Swift and Leon Michels break down how they made the song Put a Flower in Your Pocket, and how its title was inspired by a three-year-old girl.

Plus: the story behind the Radiotopia logo, and the sounds that went into making it.
