Rock music is a genre of popular music that developed during and after the 1960s, particularly in the United Kingdom and the United States. It has its roots in 1940s and 1950s rock and roll, itself heavily influenced by rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as blues and folk, and incorporated influences from jazz, classical and other musical sources.

Musically, rock has centered around the electric guitar, usually as part of a rock group with bass guitar and drums. Typically, rock is song-based music usually with a 4/4 time signature utilizing a verse-chorus form, but the genre has become extremely diverse and common musical characteristics are difficult to define. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political in emphasis. The dominance of rock by white, male musicians has been seen as one of the key factors shaping the themes explored in rock music. Rock places a higher degree of emphasis on musicianship, live performance, and an ideology of authenticity than pop music.

Lauren Bennett (born 23 June 1989) is a British singer, dancer and model. She is best known for her involvement with girl group the Paradiso Girls and her work with Cee Lo Green and LMFAO. She is the new lead singer in the new line-up of the Pussycat Dolls.

Bennett was part of a girl group called Paradiso Girls. The group consisted of seven members at its formation in 2007, but by 2008 it had dropped to five. Each member comes from a different country: Chelsea Korka from the United States, Aria Crescendo from France, Kelly Beckett from Barbados, Shar Mae Amo from the Philippines and Lauren herself from the United Kingdom. The band was signed to Interscope Records. Their debut single "Patron Tequila" featuring Lil’ Jon and Eve was released on 12 May 2009 and reached 3 on the Hot Dance Club Play Chart and 82 in Canadian Hot 100. After their second single, "Who's My B***" was unsuccessful, the group was put on an indefinite hiatus in 2010.

Tina Turner (born Anna Mae Bullock; November 26, 1939) is an American singer and actress whose career has spanned more than 50 years. She has won numerous awards. Turner started out her music career with husband Ike Turner as a member of the Ike & Tina Turner Revue. Success followed with a string of hits including "River Deep, Mountain High" and the 1971 hit "Proud Mary". With the publication of her autobiography I, Tina (1986), Turner revealed severe instances of spousal abuse against her by Ike Turner prior to their 1976 split and subsequent 1978 divorce. After virtually disappearing from the music scene for several years following her divorce from Ike Turner, she rebuilt her career, launching a string of hits beginning in 1983 with the single "Let's Stay Together" and the 1984 release of her fifth solo album Private Dancer.

Her musical career led to film roles, beginning with a prominent role as The Acid Queen in the 1975 film Tommy, and an appearance in Sgt. Pepper's Lonely Hearts Club Band. She starred opposite Mel Gibson as Aunty Entity in Mad Max Beyond Thunderdome for which she received the NAACP Image Award for Outstanding Actress in a Motion Picture, and her version of the film's theme, "We Don't Need Another Hero", was a hit single. She appeared in the 1993 film Last Action Hero.

Charles Edward Anderson "Chuck" Berry (born October 18, 1926) is an American guitarist, singer and songwriter, and one of the pioneers of rock and roll music. With songs such as "Maybellene" (1955), "Roll Over Beethoven" (1956), "Rock and Roll Music" (1957) and "Johnny B. Goode" (1958), Chuck Berry refined and developed rhythm and blues into the major elements that made rock and roll distinctive, with lyrics focusing on teen life and consumerism and utilizing guitar solos and showmanship that would be a major influence on subsequent rock music.

Born into a middle class family in St. Louis, Missouri, Berry had an interest in music from an early age and gave his first public performance at Sumner High School. While still a high school student he served a prison sentence for armed robbery between 1944 and 1947. On his release, Berry settled into married life and worked at an automobile assembly plant. By early 1953, influenced by the guitar riffs and showmanship techniques of blues player T-Bone Walker, he was performing in the evenings with the Johnnie Johnson Trio. His break came when he traveled to Chicago in May 1955, and met Muddy Waters, who suggested he contact Leonard Chess of Chess Records. With Chess he recorded "Maybellene"—Berry's adaptation of the country song "Ida Red"—which sold over a million copies, reaching No. 1 on Billboard's Rhythm and Blues chart. By the end of the 1950s, Berry was an established star with several hit records and film appearances to his name as well as a lucrative touring career. He had also established his own St. Louis-based nightclub, called Berry's Club Bandstand. But in January 1962, Berry was sentenced to three years in prison for offenses under the Mann Act—he had transported a 14-year-old girl across state lines.
