Alisan Porter

Born to Jewish parents in Worcester, Massachusetts, Porter is the great-granddaughter of prominent Worcester rabbi Joseph Klein. Her grandmother ran the Charlotte Klein Dance Center. Porter's father, Ric Porter, was co-founder, lead singer, and songwriter of the Worcester-based band Zonkaraz. Her mother, Laura Klein, also taught dance, coaching Diane and Elaine Klimaszewski, who appeared on Star Search in 1987 in the junior dance category before they became known as the Coors Light Twins. While in Los Angeles for the twins' appearance on Star Search, the show's producer heard Porter singing in the hotel lobby and booked her to appear on the next episode. Porter has been singing and performing since age three; at age five, she became the youngest Star Search participant ever to win the competition. That same year, she also appeared on Pee Wee's Playhouse as one of the playhouse gang in Season 2.

Porter acted in several films as a child; she became known for playing the title role in the 1991 movie Curly Sue opposite Jim Belushi. On television, she played the youngest daughter of Lynn Redgrave on the short-lived ABC sitcom Chicken Soup in 1989. The following year, she was slated to be a new regular cast member on Perfect Strangers, but her character was dropped after only one episode.

Porter continued acting at Staples High School in Westport, Connecticut, where she joined a theater group and participated in various shows. While a freshman, Porter portrayed Anita in West Side Story, and as a senior played the lead in Cinderella. After Porter won The Voice in 2016, her former high school drama teacher said she was not surprised by the result. "She blew everybody away" with her performance in West Side Story, and "really seemed to get the best out of everybody else. Her energy rubbed off on everybody. She inspired others."

When she was 18 years old, Porter moved to New York to audition for Broadway shows. She was cast as Urleen in the show Footloose. Following her move to Los Angeles, Porter starred as Miriam in The Ten Commandments: The Musical at the Kodak Theatre alongside Val Kilmer, Adam Lambert and Broadway star Lauren Kennedy. Variety rated her performance of the song "Light of a New Day" as "superb".

In 2003, the band The Raz was formed, with Porter as the vocalist and main songwriter. The Raz split up in 2004. In March 2005, she announced the birth of her new band, The Alisan Porter Project. During 2006, she performed in the revival of A Chorus Line as Bebe Benzenheimer at the Gerald Schoenfeld Theatre in New York City. On October 9, 2009, her independent debut album Alisan Porter was released.

Porter sang the National Anthem at the 2016 A Capitol Fourth special on July 3 at the U.S. Capitol West Lawn in Washington, D.C. The special was broadcast on PBS. She also sang the anthem prior to the nationally televised Sunday Night Football game in Oakland, CA on November 6, 2016.

In 2017, Porter, alongside Matt McAndrew, Mary Sarah, Chris Mann, Matthew Schuler, Michael Sanchez and Chloe Kohanski headlined the new Las Vegas show called The Voice: Neon Dreams.
