The 30-year-old entertainer and coach on The Voice has been in NYC since arriving in town over the weekend.

The Voice creator Mark Burnett filled EW in on what to expect next from the show – including battle rounds where contestants will sing the same songs for comparison purposes!

“The battle rounds go up a notch, it’s a huge set – artistically and physically,” Mark said. “Every performance will feel like a Grammys performance.”
