Problem: Background: The Clark Sisters are an American gospel vocal group consisting of five sisters: Jacky Clark Chisholm (b. 1948), Denise Clark Bradford (b. 1953), Elbernita "Twinkie" Clark-Terrell (b. 1954), Dorinda Clark-Cole (b. 1957), and Karen Clark Sheard (b. 1960). The Clark Sisters are the daughters of gospel musician and choral director Mattie Moss Clark. They are credited for helping to bring gospel music to the mainstream and are considered as pioneers of contemporary gospel.
Context: The Clark Sisters were born and raised in Detroit, Michigan. They each began singing at an early age, and by the late 1960s they were all performing together in church services, usually singing songs written and arranged by their mother. A few years later, Dr. Mattie Moss Clark turned over control of the group to Twinkie, who would then go on to write, arrange, conduct, and produce all of the Clark Sisters' recordings. In 1973, the sisters recorded their first album, Jesus Has A Lot To Give, on their uncle's local label Billesse Records. The following year, Dr. Mattie Moss Clark Presents The Clark Sisters was released and people around Detroit began to take notice of the group. The Clark Sisters signed to Sound of Gospel Records in 1974. Under this association, the group released albums such as Unworthy, Count It All Joy, and He Gave Me Nothing to Lose. It was not until the early 1980s that The Clark Sisters began to become more widely known. Their popularity soared with the release of the live recording Is My Living In Vain. The first live recording by The Clark Sisters spent an entire year at number one on Billboard's Gospel Music chart. Opening with the bluesy title track, each sister vocally declares that their dedication to Christ is not a useless effort. The innovative "Hi ya" was funky enough to find its way into a Tonex produced track over two decades later. Karen Clark's lead on "Speak Lord" expresses deep faith while the call to worship is raised on "Now Is The Time". Another hit from this release, "Expect Your Miracle", is still a staple in black churches across the country. Their next release You Brought the Sunshine would prove to be a monster hit via the title track. Reminiscent of Stevie Wonder's "Master Blaster (Jammin')," the song became a hit in church houses and on dance floors, including New York's Studio 54. "Sunshine" was picked up from its original independent gospel record label Sounds of Gospel and distributed by both Westbound Records and Elektra Records. In 1983, the song peaked at #16 on the Black Singles chart, #27 on the Club Play Charts, and #80 on the Hot R&B Charts driving the album to Gold sales. This album continues to display Twinkie's signature blend of scripture with unprecedented vocal and musical arrangements on biblically based songs like "Psalms 31." The album's other songs include the sincere prayer found within the lyrics of both "Center of Thy Will" and "Endow Me," featuring a young but already vocally mature Karen, as well as "Overdose of the Holy Ghost", showcasing Dorinda's vocal dexterity. The disco-inspired "He Keeps Me Company" is noted for its bubbly syncopation. The sisters delivered another progressive effort in 1982, Sincerely, which included "Name It And Claim It" and the politically charged "World." Though its success was overshadowed by the previous hit "You Brought The Sunshine", the album received a Grammy nomination.

Answer:

Problem: Background: Rouvas was born on 5 January 1972 in the village of Mandoukion, near Corfu City on the island of Corfu, the eldest of four sons of Konstantinos "Kostas" Rouvas (an ambulance driver) and the teenaged Anna-Maria Panaretou (a duty-free shop clerk at the local airport). He has three brothers: Billy (b. Vasilios), Tolis (b. Apostolos, 1975) and Nikos (b. Nikolaos, 1991). The family was poor, and Rouvas began taking care of his brothers at age five. At age four, he exhibited athletic ability and took ballet classes as a child.
Context: In December 1998 Rouvas released his sixth album (the first with his new label): Kati Apo Mena (Something From Me), written by Giorgos Theofanous. "Den Ehi Sidera I Kardia Sou" ("Your Heart Doesn't Have Steel Rails") was a hit, and remains one of his most-popular songs. To promote the album Rouvas performed at the Virgin Megastore in Athens, where thousands of fans created a traffic jam. The next year, Rouvas records "Oso Exo Esena" ("As Long As I Have You"), a duet with singer Stelios Rokkos. The two artists work and perform together at Bio Bio in Athens during the summer. In March 2000 Rouvas released his seventh album, 21os Akatallilos (21+ X-Rated), and performed with Katy Garbi at Pili Axiou in Thessaloniki. The album and its first single, "Andexa" ("I Held Out"), reached number one on the charts. During May rehearsals for summer performances Rouvas was hospitalized with abdominal pain, which was diagnosed as peritonitis and required an appendectomy. On 25 October 2000, he began appearing with Antonis Remos and Peggy Zina at Apollonas for the winter season. That year Rouvas became the Pepsi spokesperson for the company's Greek summer campaign making a first television ad, a first for a Greek entertainer. His collaboration with Pepsi continued into 2001, with a May television ad. The advertisement, featuring a semi-nude Rouvas holding a Pepsi bottle in front of his genitals, was controversial among women's rights and parental associations. Calling it "unsightly, vulgar and unacceptable", they tried to have the ad blocked as "disgrac[ing] childhood innocence and dignity." The Pepsi Tour 2001, of seven Greek cities, followed. During summer 2000 Rouvas, Psinakis and a number of other celebrities visited Mykonos on a yacht borrowed from a local physician. They were accused of drug possession, since the yacht contained narcotics. The incident was publicized amid speculation that Rouvas might have a drug addiction. Although the doctor admitted that the narcotics were his, his guests were questioned. Wishing to avoid court, Rouvas paid a fine and minimized the incident. However, thousands of T-shirts were printed which read: "Imoun ki ego sto kotero!" ("I was on the yacht, too!").
