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.

Neil Diamond (born January 24, 1941) is an American singer-songwriter with a career spanning over five decades from the 1960s until the present.

As of 2001, Diamond had sold over 115 million records worldwide including 48 million in the United States alone. He is considered to be the third most successful adult contemporary artist ever on the Billboard chart behind Barbra Streisand and Elton John. His songs have been covered internationally by many performers from various musical genres.

Diamond was inducted into the Songwriters Hall of Fame in 1984 and into the Rock and Roll Hall of Fame in 2011. Additionally, he received the Sammy Cahn Lifetime Achievement Award in 2000 and in 2011 was an honoree at the Kennedy Center Honors. He has eight number one hit singles with "Cracklin Rosie", "Song Sung Blue", "Desiree", "You Don't Bring Me Flowers", "Love on the Rocks", "America", "Yesterday's Songs", and "Heartlight".

Diamond continues to record and release new material and maintains an extensive touring schedule as well.

George "Buddy" Guy (born July 30, 1936) is an American blues guitarist and singer. Critically acclaimed, he is a pioneer of the Chicago blues sound and has served as an influence to some of the most notable musicians of his generation. "A key influence on Eric Clapton, Jimi Hendrix and Stevie Ray Vaughan, Buddy Guy put the Louisiana hurricane in 1960s electric Chicago blues as a member of Muddy Waters' band and as a house guitarist at Chess Records. A native of the Baton Rouge area, he combined a blazing modernism with a fierce grip on his roots, playing frantic leads heavy with swampy funk on Howlin' Wolf's 'Killing Floor' and Koko Taylor's 'Wang Dang Doodle' as well as on his own Chess sides and the fine series of records he made with harp man Junior Wells. One of the last active connections to the golden age of Chess, Guy still plays with his original fire."

Ranked thirtieth in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time", Guy is known for his showmanship on stage: playing his guitar with drumsticks or strolling into the audience while playing solos. His song "Stone Crazy" was ranked seventy-eighth in list of the 100 Greatest Guitar Songs of All Time also of Rolling Stone.
