AceShowbiz - "America's Got Talent" returned for the final night of season 19 Quarterfinals. Airing on Tuesday, September 3, the episode featured the last 11 acts performing in front of the judges, Simon Cowell, Sofia Vergara, Heidi Klum and Howie Mandel, with Simon possessing the control of tonight's Golden Buzzer.

Kicking off the episode was Aussie dance crew Brent Street. The 31-member group used small stages on wheels to create a dynamic performance space that took the audience eye all over the stage. Sofia was impressed, calling them "not a regular dance group."

A family of acrobats, Illya & Anastasia, hit the stage next. Their performance that night involved Illya balancing upside down with his head on two stacked bowling balls. Later, he had one single finger stuck in the top of a champagne bottle right in front of the judges' table. Simon, however, said that he's "really, really disappointed" because it "didn't feel big enough."

Swedish singer Oscar Stembridge followed it up, singing another original song. Sofia admitted that she wasn't a fan of the song, but said he's "already a superstar." Howie agreed, adding that he picked the wrong song that "isn't going to be memorable." Magician Jonathan Burns, meanwhile, played off of the Houdini straight-jacket escape trick as he folded inside a sleeper sofa by Terry instead. Simon wasn't impressed as he hit his red X buzzer before Jonathan could finish his performance.

Vocal group L6 performed next, hitting the stage to sing their rendition of "Rewrite the Stars" from "The Greatest Showman". While acknowledging their talent, Howie called them "corny" and "not of today." Sofia, on the other hand, noted that they "look sure of what they're doing" and they make her smile.

Later, Tonikaku showcased his skills by using angles and tricks of body placement to make it look as if he's naked on stage, While Heidi didn't seem to be satisfied enough, Sofia said he's "the gift that keeps giving." As for Simon, he dubbed Tonikaku one of his "favorite ever."

Irish singer-songwriter Stephanie Rainey then took the stage to sing an original song "Woman", which was inspired by her mother's fight with cancer. Sofia loved it, calling her voice "so amazing." Simon and Howie didn't think the song was grand, but they thought it would be enough to get her through.

Later, host Terry Crews revealed that Sebastian and Sofia experienced "a set back" during rehearsal. Sebastian was forced to perform alone because Sofia fell and fractured her arm. Despite the accident, Sebastian managed to wow the judges. Not stopping there, Simon gave the pair his Golden Buzzer that sent them straight to the Finals.

Quick change artist Solange Kardinaly performed next, hoping to "surprise the audience and the judges" by changing her act drastically from her audition. She also incorporated up close magic to her performance that night. Sofia thought it was "perfection," while Howie said that if America didn't vote for her, they were nuts.

Concluding the night was Heidi's 10-year-old Golden Buzzer singer Pranysqa Mishra who sang a cover of "Wrecking Ball". Sofia praised Pranysqa for making the song her own and applauded her confidence. Simon said that she sounded amazing.
