Music superstars - Gloria Estefan, John Rich, Nelly, and Joe Jonas – will have 72 hours to mentor four local musicians. Each superstar will not only groom their contestant musical, but will take over their life, tagging along with them everywhere they go. At the end of each episode, the contestants will perform at a local venue. The winner will move on to represent their city in the semi-finals. The vocalist left standing at the finals will receive a recording contract with Atlantic Records.
