On tonight's (March 5) battle round of 'The Voice,' coach Christina Aguilera had Jesse Campbell, the singer for whom all the coaches turned their chairs around during the blind auditions, go against preacher's son Anthony Evans. It was a classic David vs. Goliath, favorite vs. underdog showdown for two gospel-style vocalists as they belted out Alicia Keys' 'If I Ain't Got You.' So who slayed who? Jesse took it, but only in the 15th round. It was that close.
