The Voice UK discography: The Voice UK is the British version of "The Voice of Holland", a television talent show, along the lines of "The X Factor".  This talent show was created by John de Mol and features four coaches looking for a talented new artist, with the intent that a potential auditionee could become a global superstar.  The show's concept is simple; the auditionee walks on to the stage with the judges' backs turned to them, rendering looks, personalities, stage presence or dance routines irrelevant, and starts singing.  If the judges like what they hear, they will turn around, indicating intent to coach them.  If more than one coach turns round, power falls into the hands of the singer.  Once all four teams are complete, the live shows begin and the singers sing songs chosen for them by the coaches.
