After a respectable 2011 debut that sold 150,000 tickets over 19 dates behind headliners like Kaskade and Skrillex, Live Nation's touring Identity Festival is back for a second year. The tour kicks off July 19 in Cincinnati, Ohio, with headliners Eric Prydz and Wolfgang Gartner. And while ticket sales are up, and still moving briskly (the Jones Beach, N.Y. show sold out the day it went on sale), its most impressive bullet point might be its marketing success.
