Once again, Alisan Porter left it all on the stage Monday evening on The Voice.

The Curly Sue actress, who has openly discussed her past struggles with alcohol, performed Demi Lovato‘s “Stone Cold” and was given a standing ovation by the audience, including all four judges.

“I think this was just an emotional connection for me, this song,” Porter, 34, told PEOPLE after her performance. “I cared a little bit less about a perfect vocal and more about the emotional connection. I really relate to the song. It was easy to feel what I was talking about.”

Porter, who landed a spot on Christina Aguilera‘s team, says that her journey on The Voice has already proven to be a learning experience.

“We definitely go through a huge learning process from our first rehearsal with our coaches until we step on stage,” says Porter. “Songs have been changed, songs have been completely different. I did stuff tonight that I never did in rehearsal which kind of happens. It’s never negative, but there’s definitely constructive criticism along the way.”

And Porter wasn’t the only one to shock the crowd with a jaw-dropping performance.

Sixteen-year-old Shalyah Fearing closed the show with a beautiful rendition of Kelly Clarkson’s “Up to the Mountain.”

“That song was sort of a testimony for me because I have been climbing my own mountain,” Fearing told PEOPLE backstage. “I’ve been climbing it for a long time. I believe we all have our own mountains that we climb and we’re just barely at the top. That was my testimony.”

The Voice airs Mondays and Tuesdays at 8 p.m. on NBC.
