The band that New York Magazine coined, “the greatest Power-Pop band ever to masquerade as Metal,” Def Leppard, returns to the road this summer for an extensive North American tour. The Live Nation-promoted tour hitting nearly 50 cities across the U.S. and Canada, including Mohegan Sun Arena for a Sunday, July 5th concert beginning at 7:00pm, will kick off on June 23rd in Tampa, Florida. Joining Def Leppard on their massive summer outing are rockers Styx and Tesla.
