Emma Willis hosts the seventh series of the singing contest, which this year sees Olly Murs joining returning coaches Will.i.am, Tom Jones and Jennifer Hudson on the famous spinning chairs. The search for a star kicks off, as usual, with the first in a series of rounds of blind auditions, as the panel listen to each contestant with their backs turned, ensuring that they judge the performance on the strength of vocal ability alone. Those who succeed here will progress to the Battle and Knockout phases.
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.
