Back for its eighth year, the Rock the Bells concert series kicked off last night in San Bernardino, California with artists like Erykah Badu, Raekwon, Ghostface Killah, and Common as just a few of the headliners. Also on the bill were Lauryn Hill and Nas, who ended up taking the stage together to perform their hit “If I Ruled the World.” Watch their performance below.
