From her hometown of San Juan, Puerto Rico, Calma Carmona delivers a bewitching Tiny Desk performance. Her voice rarely rises above a whisper as she sings over impassioned Afrobeats during her three-song set — but when it does, it's a gritty, intimidating growl. Carmona got her start in 2013 when the Latin soul singer-songwriter released her first EP and opened for Beyoncé's The Mrs. Carter Show World Tour in Puerto Rico.
