Question:
Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin.
Perry completed her General Educational Development (GED) requirements at age 15, during her freshman year of high school, and left Dos Pueblos High School to pursue a musical career. She briefly studied Italian opera at the Music Academy of the West in Santa Barbara. Her singing caught the attention of rock artists Steve Thomas and Jennifer Knapp from Nashville, Tennessee, who brought her there to improve her writing skills. In Nashville, she started recording demos and learned how to write songs and play guitar. After signing with Red Hill Records, Perry recorded her debut album, a gospel record titled Katy Hudson. She released the album on March 6, 2001, and went on tour that year as part of Phil Joel's Strangely Normal Tour while also embarking on other performances of her own in the United States. Katy Hudson received positive reviews from critics, though was commercially unsuccessful and sold an estimated 200 copies before the label ceased operations in December. Transitioning from gospel music to secular music, Perry started writing songs with producer Glen Ballard, and moved to Los Angeles at age 17. In 2003, she briefly performed as Katheryn Perry to avoid confusion with actress Kate Hudson. She later adopted the stage name Katy Perry, using her mother's maiden name.  In 2004, Perry signed to Ballard's label, Java, which was then affiliated with The Island Def Jam Music Group. She began work on a solo record, but the record was shelved after Java was dropped. Ballard then introduced Perry to Tim Devine, an A&R executive at Columbia Records, and she was signed as a solo artist. Over the course of the next two years, Perry wrote and recorded material for her Columbia debut, and worked with songwriters including Desmond Child, Greg Wells, Butch Walker, Scott Cutler, Anne Preven, The Matrix, Kara DioGuardi, Max Martin and Dr. Luke. In addition, after Devine suggested that songwriting team The Matrix become a "real group", Perry recorded with them. Perry was dropped from Columbia in 2006 as her record neared completion. After the label dropped her, she worked at an independent A&R company called Taxi Music.  Perry had minor success prior to her breakthrough. One of the songs she had recorded for her album with Ballard, "Simple", was featured on the soundtrack to the 2005 film The Sisterhood of the Traveling Pants. She provided backing vocals on Mick Jagger's song "Old Habits Die Hard", which was included on the soundtrack to the 2004 film Alfie. In September 2004, Blender named Perry "The Next Big Thing". She recorded background vocals on P.O.D.'s single "Goodbye for Now" and was featured at the end of its music video in 2006. That year, Perry also appeared in the music video for "Learn to Fly" by Carbon Leaf, and played the love interest of her then-boyfriend, Gym Class Heroes lead singer Travie McCoy, in the band's music video for "Cupid's Chokehold".

Question:
Emilie Autumn Liddell (born on September 22, 1979), better known by her stage name Emilie Autumn, is an American singer-songwriter, poet, violinist, and actress. Autumn's musical style has been described by her as "Fairy Pop", "Fantasy Rock" or "Victoriandustrial". It is influenced by glam rock and from plays, novels, and history, particularly the Victorian era. Performing with her all-female backup dancers
Emilie Autumn was born in Los Angeles, California, on September 22, 1979. Autumn grew up in Malibu, California, and according to her, "being surrounded by nature and sea had a lot to do with [her] development as a 'free spirit.'" Her mother worked as a seamstress, and she has said that her father was a German immigrant with whom she did not share a close relationship. While not musicians, her family enjoyed various genres of music.  When she was four years old, she started learning the violin, and later commented: "I remember asking for a violin, but I don't remember knowing what one was. I might have thought it was a kind of pony for all I know, but I don't remember being disappointed." Four years later, Autumn made her musical debut as a solo violinist performing with an orchestra, and won a competition. At the age of nine or ten, she left regular school with the goal of becoming a world-class violinist. On her time at the school, she remarked, "I hated it anyway, what with the status as 'weird,' 'antisocial,' and the physical threats, there seemed to be no reason to go anymore, so I just didn't." She practiced eight or nine hours a day, had lessons, read a wide range of literature, participated in orchestra practice, and was home-schooled. Growing up, she owned a large CD collection of "violin concertos, symphonies, chamber music, opera, and a little jazz". She began writing her own music and poetry at age thirteen or fourteen, though she never planned to sing any of her songs. She studied under various teachers and attended Indiana University in Bloomington, but left after two years there, because she disagreed with the prevailing views on individuality and classical music. She believed that neither the audience nor the original composer would be insulted by the clothing and appearance of the performer.  While convinced that she would only play violin, eighteen-year-old Autumn decided to sing on one of her songs as a way of demonstrating to a major music producer, who wanted to sign her on a label, how it should sound. She became unhappy with the changes done to her songs, and decided to break away from the label and create her own independent record label, Traitor Records. Through it, she debuted with her classical album On a Day: Music for Violin & Continuo, which she recorded in 1997 when she was seventeen years old; its title refers to the fact that the album took only a day to record. It consists of her performing works for the baroque violin accompanied by Roger Lebow on the baroque cello, Edward Murray on harpsichord, and Michael Egan on lute. She considered it "more of a demo despite its length", and released it as "a saleable album" after fans who enjoyed her "rock performances starting asking for a classical album so that they could hear more of the violin." She also debuted with her poetry book Across the Sky & Other Poems in 2000, later re-released in 2005 as Your Sugar Sits Untouched with a music-accompanied audiobook.
