The singers who made it through the audition stages face another round of head-to-head performances, as the second night of the Battles phase arrives. Here, the would-be stars must once again demonstrate their skill to coaches Tom Jones, Will.i.am, Olly Murs and Jennifer Hudson if they are to remain in the contest. As ever, the coaches are also armed with 'saves', which give them a chance to recruit any of their colleagues' knocked-out performers to their own teams.
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.
