George Roger Waters (born 6 September 1943) is an English musician, singer-songwriter and composer. He was a founder member of the progressive rock band Pink Floyd, serving as bassist and co-lead vocalist. Following the departure of bandmate Syd Barrett in 1968, Waters became the band's lyricist, principal songwriter and conceptual leader. The band subsequently achieved worldwide success in the 1970s with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals and The Wall. Although Waters' primary instrument in Pink Floyd was the bass guitar, he also experimented with synthesisers and tape loops and played rhythm guitars in recordings and in concerts. Amid creative differences within the group, Waters left Pink Floyd in 1985 and began a legal battle with the remaining members over their future use of the group's name and material. The dispute was settled out of court in 1987, and nearly eighteen years passed before he performed with Pink Floyd again. It is estimated that as of 2010, the group have sold over 200 million albums worldwide, including 74.5 million units sold in the United States.

David Jon Gilmour,CBE (born 6 March 1946) is an English rock musician and multi-instrumentalist who is best known as the guitarist, one of the lead singers and main songwriters in the progressive rock band Pink Floyd. It is estimated that as of 2010, the group have sold over 250 million records worldwide, including 74.5 million units sold in the United States.

In addition to his work with Pink Floyd, Gilmour has worked as a producer for a variety of artists, and has enjoyed a successful career as a solo artist. Gilmour has been actively involved with many charities over the course of his career.

In 2003, he was appointed CBE for his charity work and was awarded with the Outstanding Contribution title at the 2008 Q Awards. In 2011, Rolling Stone Magazine ranked him number 14 in their list of the greatest guitarists of all time.

Gilmour was born in Cambridge, England. His father, Douglas Gilmour, was a senior lecturer in zoology at the University of Cambridge and his mother, Sylvia (née Wilson), was a teacher and film editor who raised her family at Grantchester Meadows, later immortalised by a Roger Waters song on Pink Floyd's Ummagumma. He has a younger brother who is also a musician.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
