Sandra Faye "Sandi" Patty (born July 12, 1956) is an American Christian music singer, known for her wide vocal range and expressive flexibility which has led music critics to dub her "The Voice". 　　Patty recorded her first album, For My Friends, an independent effort, that landed in the hands of executives at Singspiration! records. In 1979, she was signed to Singspiration! and released her first professional record, Sandi's Song. According to the FAQ section on her website, the name on her birth certificate is Sandra Patty. A printer's error on the labeling listed her name as Sandi Patti, and she used this moniker as her stage name for the next fifteen years, before correcting it to Sandi Patty. 　　Patty's career expanded after she won her first two GMA Dove Awards in 1982 and began singing backup for Bill Gaither and the Bill Gaither Trio. She headlined her first national tour in 1984 and reached national acclaim after her rendition of "The Star-Spangled Banner" was included during the ABC Statue of Liberty re-dedication broadcast on July 6, 1986. This exposure led to multiple mainstream television appearances including The Tonight Show, Christmas in Washington, Walt Disney's Fourth of July Extravaganza, and the 1998 Pepsi 400; the clip was frequently used on television sign-offs for the remainder of their existence. She was invited to sing the national anthem at the Indianapolis 500 in 1987–88, 1990–92, and once again in 2013. 　　At the peak of her career, Patty's concerts were so heavily attended that she performed in often sold-out mainstream arenas and concert halls. In the late 1980s and early 1990s, she averaged over 200 concerts a year, and supported a staff of over 30 that managed her career. During this period of time Patty was noted, often critically, as the highest-paid singer in the Christian music industry averaging over $100,000 per appearance, largely due to massive touring and high-profile public appearances.
