The new podcast Anything for Selena, from NPR member station WBUR, doesn't begin with the late singer's biography or her most popular songs. Instead, it starts on the U.S.-Mexico border, with a narrator describing the creosote plants that grow there in vivid sensory terms.
"It has this unforgettable smell when it rains," the voice says. "It's slightly floral, but mostly it's this very specific, cool earthy desert aroma. And there's usually a calm clear breeze, which carries these concentrated little pockets of fragrance."
