Katy Perry - E.T. , Firework

Katy Perry (born Katheryn Elizabeth Hudson; October 25, 1984) is an American singer-songwriter and actress. Born in Santa Barbara, California, and raised by Christian pastor parents, Perry grew up listening to only gospel music and sang in her local church as a child. After earning a GED during her freshman year of high school, she began to pursue a career in music.

As Katy Hudson, she released a self-titled gospel album in 2001, which due to the closing of her record label, was deemed unsuccessful. She later recorded an album with production team The Matrix and completed the majority of a solo album from 2004–5, neither of which were released.

After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry and released her first Internet single "Ur So Gay" that November, which garnered public attention but failed to chart. She rose to fame with the release of her second single "I Kissed a Girl" in 2008, which went on to top international charts.

Perry's first mainstream studio album One of the Boys followed later that year and subsequently, became the thirty third-best selling album worldwide of 2008. It was accredited platinum certification by the Recording Industry Association of America, while "I Kissed a Girl" and her second single "Hot n Cold" both received multi-platinum certifications.

Her sophomore studio album Teenage Dream was released in August 2010 and debuted at number one on the Billboard 200. The album included hit singles "California Gurls", "Teenage Dream", "Firework" and "E.T." , all of which topped the charts on the Billboard Hot 100, making the Teenage Dream album one of only nine albums to ever produce four or more Hot 100 number ones.

"E.T." is an electronic ballad that tells of "falling in love with a foreigner". Extraterrestrial metaphors are used throughout, and West continues these metaphors in his two verses, making heavy use of Auto-Tune at times. Though the song was widely noted for its darker and more mature theme, in contrast to Perry's conventional works, critics were overall mixed in response.

West's presence on the single also received divided opinions. The single topped the Billboard Hot 100—the fourth from Teenage Dream to do so—for five non-consecutive weeks and is Perry's fifth number one on the chart.

"Firework" is a self-empowerment anthem with inspirational lyrics, and was considered by Perry as the most important song for her on Teenage Dream.

"Firework" received good reviews from music critics, with some noticing its catchy melody and danceable beat and comparing it to songs by English band Coldplay.

The song was commercially successful, reaching the top spot on Billboard Hot 100 and the top 5 on twenty charts around the world.

An accompanying music video, directed by Dave Meyers, was released on October 28, 2010. It portrayed Perry singing and dancing around Budapest, with intercalating scenes of shy teenagers become confident in themselves.
