About Waving Through a Window (Bonus Track)

Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television personality. 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. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007.

Katheryn Elizabeth Hudson was born in Santa Barbara, California, to Pentecostal pastors Mary Christine (née Perry) and Maurice Keith Hudson. Her parents are born again Christians, each having turned to religion after a "wild youth". Perry has English, German, Irish, and Portuguese ancestry. Through her mother, she is a niece of film director Frank Perry. She has a younger brother named David, who is a singer, and an older sister, Angela. From ages 3 to 11, Perry often moved across the country as her parents set up churches before settling again in Santa Barbara. Growing up, she attended religious schools and camps, including Paradise Valley Christian School in Arizona and Santa Barbara Christian School in California during her elementary years. Her family struggled financially, sometimes using food stamps and eating from the food bank intended to feed the congregation at her parents' church. Growing up, Perry and her siblings were not allowed to eat the cereal Lucky Charms as the term "luck" reminded their mother of Lucifer, and had to call deviled eggs "angeled eggs". Perry primarily listened to gospel music, as secular music was generally discouraged in the family's home. She discovered popular music through CDs she sneaked from her friends. While not strictly identifying as religious, Perry has stated, "I pray all the time – for self-control, for humility." Wanting to be like Angela, Perry began singing by practicing with her sister's cassette tapes. She performed the tracks in front of their parents, who let her take vocal lessons as Angela was at the time. She began training at age 9, and was incorporated into her parents' ministry, singing in church from ages 9 to 17. At 13, Perry was given her first guitar for her birthday, and publicly performed songs she wrote. She tried to "be a bit like the typical Californian girl" while growing up, and started rollerskating, skateboarding, and surfing as a teenager. Perry's brother David described her as a tomboy during her adolescence. She took dancing lessons and learned how to swing, Lindy Hop, and jitterbug.
