Alicia Keys and Sara Bareilles teamed up for City of Hope's 2019 Spirit of Life Gala in Santa Monica, and their duet brought down the house. The two traded tunes throughout their time on stage, with Keys singing "Gravity" and Bareilles giving "If I Ain't Got You" her own spin. They even engaged in a round of dueling pianos, showing off a powerhouse mashup of "Girl on Fire" and "Brave.”
I managed to find a clip that isn’t very clear and it jumps but it they sound Incredible.
