A Grammy Award (originally called Gramophone Award) – or Grammy – is an accolade by the National Academy of Recording Arts and Sciences of the United States to recognize outstanding achievement in the music industry. The annual presentation ceremony features performances by prominent artists, and some of the awards of more popular interest are presented in a widely viewed televised ceremony. It is the music equivalent to the Emmy Awards for television, the Tony Awards for stage performances, and the Academy Awards for motion pictures.

The first Grammy Awards ceremony was held on May 4, 1959, and it was set up to honor musical accomplishments by performers for the year 1958. Following the 2011 ceremony, NARAS overhauled many Grammy Award categories for 2012. The 54th Grammy Awards were held on February 12, 2012, at the Staples Center in Los Angeles, California.

The Grammy Awards had their origin in the Hollywood Walk of Fame project in the 1950s. As the recording executives chosen for the Walk of Fame (Tabinda Walk) committee worked at compiling a list of important recording industry people who might qualify for a Walk of Fame star, they realized there were many more people who were leaders in their business who would never earn a star on Hollywood Boulevard. The music executives decided to rectify this by creating an award given by their industry similar to the Oscars and the Emmys. This was the beginning of the National Academy of Recording Arts and Sciences. After it was decided to create such an award, there was still a question of what to call it; one working title was the Eddie, to honor the inventor of the phonograph, Thomas Edison. They finally settled on using the name of Edison's invention, the gramophone, for the awards, which were first given for the year 1958.

Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter and occasional actress. Raised in Wyomissing, Pennsylvania, Swift moved to Nashville, Tennessee at the age of fourteen to pursue a career in country music. She signed to the independent label Big Machine Records and became the youngest songwriter ever hired by the Sony/ATV Music publishing house. The release of Swift's self-titled debut album in 2006 established her as a country music star. "Our Song", her third single, made her the youngest sole writer and singer of a number one song on the country chart. She received a Best New Artist nomination at the 50th Grammy Awards.

Swift's second album, Fearless, was released in late 2008. Buoyed by the chart success of the singles "Love Story" and "You Belong with Me", Fearless attracted a crossover audience and became the top-selling album of 2009. The record won four Grammy Awards, with Swift becoming the youngest ever Album of the Year winner. Fearless also received Album of the Year plaudits at the American Music Awards, Academy of Country Music Awards and Country Music Association Awards, making it the most awarded album in country music history. In 2010, Swift released her third album, Speak Now, which sold over one million copies in its first week. She then embarked on the 111-date Speak Now World Tour, which was attended by over 1.6 million fans and has become one of the highest-grossing concert tours of all time. The album's third single, "Mean", won two Grammy Awards for Best Country Song and Best Country Solo Performance. Swift is currently recording her fourth studio album, due for release in the fall of 2012.

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
