Live Nation National

In support of her high-decibel new album, Rihanna kicks off her hotly anticipated LOUD tour with emphatic gusto and a sizzling roster of special guests. Like an art show at a sundae bar, the LOUD tour floods the senses, enchanting audiences with lavishly designed sets, myriad costume changes, move-busting dancers, and Rihanna's songbook of Grammy magnets. Crooner Cee Lo Green augments the songful offerings with his own vocal talents, and Roc Nation rapper and rhythm scientist J. Cole further helps resuscitate ear drums traumatized by the outside world's blaring car horns and shrill howler monkeys.
