Demonstrating its continued support of music, Levi's® Jeans announced today its sponsorship of double platinum R&B recording star D'Angelo's summer concert tour. Michael "D'Angelo" Archer will tour the States as the headlining act of Levi's® Presents D'Angelo -- the brand's second summer concert series. The tour includes a partnership with PAX, an anti-gun violence organization, designed to engage and activate youth to take a stand against the gun violence epidemic.The national tour, which begins July 29 in Chicago and travels to more than 20 markets, was announced during an event featuring D'Angelo and 2,000 students at Hamilton High School. Sharing the stage with D'Angelo to kick-off this summer's activities were Columbine High School student Devon Adams; PAX Co-founders Daniel Gross and Talmage Cooley; and PAX Students Co-Chairs Ben Gelt and David Winkler.During the event, D'Angelo was the first to sign this year's Levi's® Denim Wall to show his support for the powerful movement of PAX's Youth Petition to End Gun Violence. The petition represents America's youth and is intended to foster the implementation of common sense solutions for gun violence. This summer Gelt and Winkler will travel with the Levi's® Presents D'Angelo tour to collect signatures on the wall. Each signature collected contributes to PAX's goal of gathering one million signatures. Individuals not attending a D'Angelo show this summer can log onto
