America's Got Talent: Team iLuminate Lights Up Competition
09/07/2011 AT 09:00 AM EDT
With the top 10 acts on America's Got Talent fighting for one of the four spots in next week's final round, it was make-or-break time on Tuesday's performance show.
Team iLuminate's neon, glow-in-the-dark dance performance to electronic tunes was simply flawless.
"I don't think I've ever seen a more original, creative act," Piers Morgan told the group, while Sharon Osbourne said she "couldn't believe you're not already famous."
"You were spectacular," raved Howie Mandel. "You are always spectacular – one of the best acts you could possibly see here."
While Team iLuminate may have received the highest praise overall, other fan favorites got a stamp of approval during the night as well.
Landau Eugene Murphy, Jr. – the jazz singer who recently told PEOPLE he's "the one to beat" – also brought his A-game. "If I could pick any act to watch [in Vegas], it would be Landau," Morgan said (although he performed before Team iLuminate).
According to Morgan, young Bay Area-based music act Poplyfe "deserved" their standing ovation for their medley of Jackson 5 hits. Osbourne and Mandel also gave them two thumbs up, suggesting they should definitely be in the finals.
Silhouettes bounced back from an off week, and impressed the judges and a crowd that cheered so loud that Osbourne's comments could not be heard.
"You should be in the finals," Mandel said, while Morgan called the act – the fifth of the evening – "without a doubt, the best performance [so far] tonight."
Meanwhile, other acts struggled.
Miami All Stars dance team seemed too much like "cheerleaders," according to Morgan. Osbourne and Mandel acknowledged that the group has great dancers, but didn't think this was the performance that will take them to the finals.
Meanwhile, 11-year-old singing sensation Anna Graceman had her first off night. The judges criticized the typically praised vocalist for missing some notes during her rendition of Cyndi Lauper's "True Colors."
