When Amerie walked into the Tiny Desk, her smile alone set the stage for a summer celebration. Backed by go-go pioneers Backyard Band, she delivered a set blending old favorites like “Talkin’ to Me” and “Why Don’t We Fall in Love” with new gems like “Mine.” Surrounded by Warren Jones, Michael Dunklin, Eric Britt, Bobby Terry, Eugene Chapman, Nathaniel Fields, Paul Edwards, Keith Robinson, Tanesia Mack, Tonaee’ Burgess, and Zay’Marie, the performance pulsed with rhythm and heart. By the time “1 Thing” closed the show, Amerie had turned the Desk into a dance floor of endless possibilities.
