WATCH: Beyoncé and Eddie Vedder perform stunning duet of Marley's 'Redemption Song' at Global Festival

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."

In support of Global Citizen -- an initiative to combat extreme poverty and inequality around the world -- a star-studded cast made appearances, but none shone quite a brightly as the unlikely duo of Beyoncé and Vedder.

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.
