It's not exactly typical for artists at the Tiny Desk to share their future burial plans, but that's exactly what Indigo de Souza does halfway through her performance. "I wrote this song about my love for nature," the singer-songwriter says, introducing the track "Not My Body." "I think that when I die ... what I want is to be composted and to become soil, and for that soil to be used to plant a tree, and I want that tree to be so big and strong."
