This past weekend superstars flocked to Washington, DC for the 2015 Global Citizen Earth Day concert on the National Mall on Saturday (April 18). The star studded soiree was hosted by will.i.am and featured acts such as No Doubt, Common, Mary J. Blige and Usher.
Usher who is recovering from a recent surgery after fracturing his foot, still took to the stage to deliver a 45 minute set with crutches in tow. While Mary J. kept the crowd rocking as she belted out her hits and No Doubt kept the party going. Check out some of the clips below.
