Two of the biggest stars in Bollywood are performing in the States in what they are calling the Krazy 2 Tour. Ali Zafar is a Pakistani model turned actor turned pop star, while Sunidhi Chauhan has made a name for herself as one the biggest playback singers in India. A playback singer is someone who actually sings the songs in the movies that the actors are lip-synching to (not as common here, but really popular in India). Each performer will bring his own ensemble band and backup dancers. It'll be a fun time for sure.
