It's the first of the knockout shows as the remaining 12 acts sing for a place in the semi-finals. Coaches Will.i.am, Tom Jones, Olly Murs and reigning champion Jennifer Hudson can pick only one act from their teams to progress in the competition, so there are some tough decisions to make. Helping them are R'n'B star Craig David, members of the Black Eyed Peas, Australian pop queen Kylie Minogue, 2006 winner of The X Factor Leona Lewis and The Voice UK's reigning champion, Mo Jamil. Presented by Emma Willis.
Hosted by Emma Willis and Marvin Humes, the show features four musician coaches: will.i.am, Boy George, Paloma Faith and Ricky Wilson, who will coach only the most talented vocalists. The show's innovative format features three stages of competition: the first begins with the blind audition, then the competition enters into a battle phase, and finally, the live performance. The show's casting team is working with the music industry and searching the country for the best singers to bring to the blind audition process.
During the blind auditions, the decisions from the coaches are based solely on voice and not on looks. The coaches hear the contestants perform, but they don't get to see them - thanks to rotating chairs.
