Tuesday saw some of the toughest competition between America's Got Talent performers, who were all vying for the last seven spots in the final week of the Judge Cuts round.

From singing groups to daredevils to mind-blowing magicians, every act that hit the stage knew what was on the line and brought everything they had to impress the judges -- but despite an onslaught of stunning displays of skill, the panel still had to make their cuts.

Special guest judge Seal
helped the panel whittle down the he competition to the seven performers who impressed them the most and showed that they have what it takes to go all the way. Here are the acts that made it through to the upcoming AGT live round.

1. In The Stairwell

This a capella singing group, made up of members of the Air Force Academy, donned their flight suits to impress the judges -- especially Howie, who didn't really love their audition earlier this season -- with a super fun cover of *NSYNC's "Bye Bye Bye."

2. Pompeyo Family

What's not to love about cute kids doing tricks with adorable dogs? This Florida family of dog trainers donned their best Western wear for an energetic performance showcasing their unique canines, who can pull off some of the coolest tricks you've ever seen.

3. Johnny Manuel

This 32-year-old singer belted out a beautiful rendition of Stevie Wonder's "Lately" that impressed Mel B, but left Simon Cowell a little cold. The judge then asked Manuel to perform an a capella cover of Whitney Houston's "I Have Nothing," and the singer's ability to hit some amazing high notes impressed Seal so much he had no choice but to slam the Golden Buzzer.

4. DaNell Daymon & Greater Works

Very rarely, if ever, do gospel choirs compete on AGT, but it's a good thing Greater Works decided to, because their stage presence, energy, vocal skills and enthusiasm are revelatory. For their second round of competition, the group delivered a cover of Marvin Gaye's "Ain't No Mountain High Enough" that brought everyone in the theater to their feet.

5. Artyon and Paige

While these pint-sized performers didn't impress Simon Cowell with their well-choreographed interpretive dance routine during the auditions, they came back even stronger and won over everyone watching with their beautiful dance number set to Bill Medley and Jennifer Warnes' "(I've Had) The Time of My Life."

6. Merrick Hanna

When 12-year-old dancer Hanna took the stage, hopes were high because the judges had loved his audition so much. And the young performer didn't disappoint, proving once again that he has an almost-impossible level of control over his movements, performing a dance number as a robot in a way that evokes pain, beauty and heartache with every motion. It's unlike any other act this season.

7. Kechi

This stunning singer -- who, at 16, found a love for music in the hospital after being badly burned during a tragic plane crash -- brought the AGT audience to tears with her stirring cover of John Hiatt's "Have a Little Faith in Me." The performance earned a standing ovation and nothing but love from Seal, who joined the singer on stage to give her a hug.
