The two-time Emmy Award-winning The Voice invites talented vocalists from across the country. Be prepared once again for NBC’s number one series The Voice. Grammy winner Christina Aguilera will join megastars Pharrell Williams, Adam Levine and Blake Shelton as celebrity musician mentors. Carson Daley returns to serve as host. The show will air on the NBC as usual. Five competition stages: the blind auditions, the battle rounds, the knockouts, the live playoffs and, finally, the live performance shows. The winner will be determined by TV viewers voting by telephone, Internet, SMS, and iTunes Store purchases of the artists’ recorded performances. Candidates must be legally present in the USA and at least 15 years of age. For more information, kindly check out this link.
