Jacqueline Marie "Jackie" Evancho ( /iːˈveɪŋkoʊ/ ee-VAYNG-koh; born April 9, 2000) is an American classical crossover singer who has gained wide recognition at an early age.

Between 2008 and 2010, Evancho entered several talent competitions; made singing appearances, mostly in Pennsylvania; issued an independent album, Prelude to a Dream; and attracted interest on YouTube. Later in 2010, at the age of 10, she gained wider popularity with her performances in the fifth season of the America's Got Talent (AGT) competition, finishing in second place. With the subsequent release of her O Holy Night EP, she became the best-selling debut artist of 2010, the youngest top-10 debut artist in U.S. history and the youngest solo artist ever to go platinum. In June 2011, her first full-length major-label album, Dream With Me, debuted at #2 on American album charts, and she became the youngest top-5 debut artist in UK history. Billboard ranked Evancho the top Classical Albums Artist for 2011.

Evancho impressed composers Tim Janis and David Foster, each of whom included her in his concerts beginning in 2009. Foster later produced Evancho's album, Dream With Me, and subsequent PBS special for the television series, Great Performances. Evancho performed in front of U.S. President Barack Obama at the 2010 National Christmas Tree lighting in Washington, D.C. She is the ambassador for "Mission: Humane", a Humane Society program which encourages children's involvement in the protection of animals. She features songs from Dream With Me in a 2011–12 concert tour with symphony orchestras. Evancho released another studio album, Heavenly Christmas, in November 2011. The same month, she became the youngest person ever to give a solo concert at Lincoln Center in New York City. A national cotillion organization listed her as one of the "ten best-mannered people of 2011".

LaDonna Adrian Gaines (December 31, 1948 – May 17, 2012), known by the stage name Donna Summer, was an American singer and songwriter who gained prominence during the disco era of the late 1970s. She had a mezzo-soprano vocal range, and was a five-time Grammy Award winner. Summer was the first artist to have three consecutive double albums reach number one on the United States Billboard chart, and she also charted four number-one singles in the United States within a 13-month period.

Born into a devoutly Christian lower middle class African American family in Boston, Massachusetts, Summer first became involved with singing through church choir groups before joining a number of bands influenced by the Motown Sound. Influenced by the counterculture of the 1960s, she became the front singer of a psychedelic rock band named Crow and moved to New York City. Joining a touring version of the musical Hair, she spent several years living in West Germany, where she married Helmut Sommer, whose surname she adopted as her stage name.

John Andrew Quale is an American singer, songwriter, and performer best known by the stage name and persona of Prince Poppycock. Quale, who specializes in musical theater and opera, describes Prince Poppycock on his website as a "roguish operatic dandy."

Poppycock came to national attention in 2010 when he competed on the fifth season of America's Got Talent. On September 15, 2010, he was voted fourth place in the final four.

Quale was raised on a horse farm in Great Falls, Virginia. As a child, he sang "incessantly" and was a member of several children's choirs. His first public performance was at age 11 at Kennedy Center in the Children's Choir of the Washington National Opera. In his teenage years, Quale developed a love for writing music and became "enamored" with David Bowie, Depeche Mode, opera, madrigals, Gregorian chant, the Smiths and Gilbert and Sullivan. He also began recording his own music. While in high school, he spent several summers at Interlochen Arts Camp, a competitive performing arts program of the Interlochen Center for the Arts. His "flair for theater and arts made his teen years particularly tough," and bullying led him to drop out of high school in his junior year. Quale has since earned a GED. Quale performed and toured with musicals and choirs throughout high school and college. In December 2001, Quale joined Chicago synth-pop band Endora as lead singer and songwriter. Quale moved to Los Angeles around 2005 and studied musical theatre at the Beverly Hills Playhouse. Quale wrote and released a solo album, Worldview, and was one of several young gay performing artists profiled in Brian Gleason's documentary Rise Up and Shout!.

Before America's Got Talent, Murphy worked as a car washer. He was homeless at age 19.

Murphy was revealed as the winner of the show on September 14, 2011, after a positively received performance of "My Way", a song popularized by Frank Sinatra. He won the $1 million grand prize and will begin a headlining act in Las Vegas on October 28.
