LOS ANGELES On Saturday, Bono and the Edge, Juanes, Kenny Chesney, K’Naan, Lady Gaga, Stevie Wonder, and Usher were among the performers at the Hollywood Bowl for “A Decade of Difference,” a concert celebrating the 10th anniversary of the William J. Clinton Foundation. Control Room produced the buzzy, celebrity- and entertainer-heavy affair, which poached big names from other events around town. The event served as a charitable program to raise awareness around the foundation's efforts surrounding global issues. Tickets to the concert started at a modest $50. Bigger spenders got V.I.P. reception access and—as you might imagine—better seats.
