'America's Got Talent': Week 10, Part 1

America's Got Talent brought the last set of 12 quarterfinalists on stage on Tuesday.

Host Nick Cannon opened the show and reminded the audience (and America) that "on this show anything is possible." Then he introduced judges Piers Morgan, Sharon Osbourne and David Hasselhoff. Each expected the performers to do their best that night.

The first act to perform was Ishaara, a group that combined Bollywood with modern dance. Morgan said it was "a wonderful way to start the show," Osbourne called the group "exotic" and Hasselhoff thought the dancers were the best so far in the competition.

Barbara Pedilla, singer and cancer survivor from Houston, gave an opera rendition of Sarah Brightman's "Time to Say Goodbye" and received a standing ovation from the judges and audience. Hasselhoff said Pedilla is "spiritually blessed with a beautiful voice" and Morgan said Simon Cowell created "America's Got Talent" for talented contestants like her.

The next act was Pam Martin's Top Dogs, where a woman performed tricks with one of her six dogs, Spy. Hasselhoff said he did not think she would win the competition, but Osbourne and Morgan said they liked the performance.

The African High Flyers, performers from Kenya, set up a human pyramid among other tricks. Morgan, who hit the buzzer halfway through the performance, said it could not match up to Pedilla's singing, which he said raised the bar for the contestants who followed her.

Singer Mia Boostrom, who was voted out of the competition last season, sang Jeff Buckley's "Hallelujah" on Tuesday. Hasselhoff noted how far Boostrom has gone on the show, while Osbourne and Morgan had conflicting views on her performance. (Osbourne called it "perfect," but Morgan said there are better singers on the show.)

Erik and Rickie, kid dancing duo, performed a Paso Doble for the audience. Hasselhoff and Osbourne gave them a standing ovation. Morgan said Erik's dancing was "like a matador chasing a bull."

The next contestant, Coney Island Chris, played with fire on stage. All three judges "buzzed" him and the audience barely uttered a reaction to the silly performance. The judges said they expected a more shocking performance.

Matt and Anthony, New York college roommates and whom Cannon thinks is a "unique act," returned on stage with Matt on guitar singing "Freedom" and Anthony showing off his impressive tap dancing skills. Osbourne said an element is missing from the roommates' "gelling," and Morgan said Anthony is more talented than Matt.

The Lollipop Girls, a dance/tease act, came back as "wildcards." Their performance to "Big Spender" impressed Hasselhoff just as the audition did. Morgan called it "charming" and Osbourne said the women could have an act in Las Vegas.

Singer and guitar player Drew Stevyns was the other wildcard act. He sang the Fray's "How to Save a Life" but did not "wow" the judges. Hasselhoff said it was a "great, emotional job" and Morgan said Stevyns is not the best singer in the competition.

A group of drummers called Recycled Percussion performed with buckets and a drill on an electric guitar to "Ballroom Blitz." After the judges gave the performers a standing ovation, Osbourne thanked them for taking her advice about bringing something different to the stage. Morgan said he thinks the "load of trash" can win the competition.

The Eriam Sisters, three singing siblings, were the last to perform for America's votes. They sang Beyonce's "Crazy in Love" with three male bicycling backup dancers. Hasselhoff said the young girls should stick with the singing, Morgan said they are "the next Destiny's Child," and Osbourne added that America should keep them on the show.

Five more acts from Tuesday will complete the top 20 after "America's Got Talent" reveals the results of the votes on Wednesday.
