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". Marie Wilt (also Maria Vilda and Marie Liebenthaler) (30 January 1833 – 24 September 1891) was an Austrian dramatic coloratura soprano.  Possessing a wide vocal range with a significant amount of power and flexibility, Wilt sang a wide repertoire that encompassed the operas of Wolfgang Amadeus Mozart, the German operas of Richard Wagner, the grand operas of Giuseppe Verdi, and the bel canto operas of Bellini, Rossini, and Donizetti.  She sang for many years at the Vienna Hofoper (now Vienna State Opera) and for a number of seasons at the Royal Opera House, Covent Garden in London.

She possessed a flexible warm voice with a wide vocal range that, while focusing mostly within the mezzo-soprano repertoire, enabled her to sing roles normally associated with contraltos and sopranos. Indeed, during her lifetime she was often identified as either a mezzo-soprano or a contralto by music critics without much consistency.  While she had an excellent vocal technique and an exceptionally beautiful tone quality, her gifts as an actress and interpreter were only mediocre. A Christian music festival (also known as a Jesus music festival or simply a Jesus festival) is a music festival held by the Christian community, in support of performers of Christian music.  The festivals are characterized by more than just music; many feature motivational speakers and evangelists, and include seminars on Christian spiritual and missions topics, service, and evangelism.  They are often viewed as evangelical tools, and small festivals can draw 10 times the crowd of traditional revival meetings.  While the central theme of a Christian festival is Jesus Christ, the core appeal of a Christian music festival remains the artists and their music.  Critics point out that the dichotomy of business and religious interests can be problematic for Christian festivals.  In similar ways as the Christian music industry in general, festivals can be drawn away from their central theme and gravitate toward commercialization and mainstream acts in an attempt to draw crowds.
