This is just the coolest. Marketplace heard Joe Biden's request for a Janet Yellen tribute, and reached out to Dessa, who was on the Hamilton Mixtape, and is a member of Doomtree (a hiphop collective) to give a bump to the effort. She was all in immediately, and the result is so much damn fun. From Marketplace: Dessa told “Marketplace” host Kai Ryssdal that she spent a lot of time watching old speeches and flipping through photographs of Janet Yellen while writing the song. “I read a lot about her to make sure that she was somebody who I’d like to send up,” Dessa said.
