Each week, the singers perform a song and are eliminated based on the three judges' perception and audience voting.
This program began on July 23, 2010 and ended October 22, 2010 with the announcement of Huh Gak as the winner and Korean-American John Park as the runner-up.
The auditions took place in 8 cities across South Korea (Daejeon, Incheon, Daegu, Gwangju, Chuncheon, Jeju Island, Busan, Seoul) and Los Angeles.
In the end, John Park, Hyun Seung-hee, Kang Seung-yoon and Kim Greem successfully passed the round and joined the rest of the Top 24.
However this year, the Rival Mission took a shocking turn and became messed up as some pairs had both members eliminated due to their lacking effort.
