Fitting many people into a small space has been key to the Tiny Desk formula since its beginning, so it only makes sense that Madi Diaz would perpetuate the tradition as she presides over a “tiny living room” concert in her Nashville, Tenn. home. “Never have there been so many people in this apartment,” she notes between songs. Diaz’s living room may not have been designed to accommodate a four-piece string section and a drummer, but together these six musicians make beautiful work of four tracks from the singer-songwriter’s stunning 2021 sleeper History of a Feeling. Opening with “Resentment” — a song she’d originally co-written for Kesha’s 2020 album High Road — Diaz steers her four-song set toward History of a Feeling’s quieter moments, in the process coaxing new power from career highlights like “New Person, Old Place.”
