Emily Keener And Jonathan Bach' Battle Round Proves Exactly Why The Coaching On 'The Voice' Is The Best In The Game

It's amazing how quickly contestants can improve on The Voice. Team Pharrell contestants Emily Keener and Jonathan Bach went head to head in the Battle Rounds with Ellie Goulding's "Explosions." While their audition was certainly explosive, it was in rehearsals that they really shined. The two timid performers transformed into complete rockstars under Pharrell and Sean Diddy Combs' direction — which just goes to show how powerful the coaching sessions really are.

There's no denying that this is an incredibly talented season, but even the most talented of contestants can benefit from working with the celebrity coaches and advisors — that is why these artists audition for the show in the first place, right? Keener and Bach are living proof of that. They were good when they went in rehearsals. They probably could've gone on that stage without any coaching and still given a great performance. But under Combs' and Pharrell's guidance, they were taken to a whole other level. Bach was able to find his belt (the vocal kind, not the kind that holds up your pants) and Keener found her confidence. These new learnings took their Battle Round to the next level and made Bach and Keener better performers.

No matter how much they each progressed and deserved to move on, one contestant did have to go home. Unfortunately, that was Bach. He undoubtedly came the farthest in their coaching session, but it wasn't far enough to beat Keener. When it came down to it, her sound mixed with her newfound confidence made her the full package. Ultimately, that's what Pharrell needs to win. At only 17 years old, Keener is already an incredibly talented artist. With more coaching, there's no doubt she'll become a major threat in this competition and a huge contender in the running for The Voice title.
