James Joseph Brown (May 3, 1933 – December 25, 2006) was an American singer, songwriter, musician, and recording artist. He is the originator of funk music and is a major figure of 20th century popular music and dance.

In a career that spanned decades, Brown profoundly influenced the development of many different musical genres. Brown moved on a continuum of blues and gospel-based forms and styles to a profoundly "Africanized" approach to music making. Brown performed in concerts, first making his rounds across the Chitlin' Circuit, and then across the country and later around the world, along with appearing in shows on television and in movies. Although he contributed much to the music world through his hitmaking, Brown holds the record as the artist who charted the most singles on the Billboard Hot 100 without ever hitting number one on that chart.

For many years, Brown's touring show was one of the most extravagant productions in American popular music. At the time of Brown's death, his band included three guitarists, two bass guitar players, two drummers, three horns and a percussionist. The bands that he maintained during the late 1960s and 1970s were of comparable size, and the bands also included a three-piece amplified string section that played during ballads. Brown employed between 40 and 50 people for the James Brown Revue, and members of the revue traveled with him in a bus to cities and towns all over the country, performing upwards of 330 shows a year with almost all of the shows as one-nighters. In 1986, he was inducted into the Rock and Roll Hall of Fame and in 1990 into the Songwriters Hall of Fame.

Sir Michael Philip "Mick" Jagger, (born 26 July 1943) is an English musician, singer, songwriter and actor, best known as the lead vocalist and a founder member of The Rolling Stones.

Jagger's career has spanned over fifty years. Allmusic has described Jagger as "one of the most popular and influential frontmen in the history of rock & roll". His distinctive voice and performance, along with Keith Richards' guitar style, have been the trademark of The Rolling Stones throughout the career of the band. In 1989, he was inducted into the Rock and Roll Hall of Fame with The Rolling Stones.

Jagger gained much press notoriety for admitted drug use and romantic involvements, and was often portrayed as a counterculture figure. In the late 1960s Jagger began acting in films (starting with Performance and Ned Kelly), to mixed reception. In 1985, Jagger released his first solo album, She's the Boss, and was knighted in 2003. In early 2009, he joined the eclectic supergroup SuperHeavy.

Jagger was born into a middle class family at Livingstone Hospital, in Dartford, Kent, England. His father, Basil Fanshawe ("Joe") Jagger (13 April 1913 – 11 November 2006), and his grandfather David Ernest Jagger were both teachers. His mother, Eva Ensley Mary (née Scutts; 6 April 1913 – 18 May 2000), born in New South Wales, Australia, was a hairdresser and an active member of the Conservative Party. Jagger is the elder of two sons (his brother Chris Jagger was born on 19 December 1947) and was raised to follow in his father's career path.
