Performing a duet at the Global Citizen Festival in New York on Saturday night, Beyoncé and Pearl Jam frontman Eddie Veffer turned in a stunning cover of Bob Marley’s “Redemption Song.”

Performing with only an acoustic guitar, the two traded verses, before a video clip of the late South African President Nelson Mandela was shown on the big screens explaining how he grew up in extreme poverty.
