Choi Seung-hyun (Korean: 최승현; born November 4, 1987), better known by his stage name T.O.P (Korean: 탑), is a South Korean recording artist and actor. Best known as a lead rapper of the hip hop Korean boy band Big Bang, he has branched out to act in various dramas and films, including I Am Sam, Iris, Nineteen and 71: Into the Fire.

In 2011, T.O.P and bandmate, G-Dragon collaborated to record and release the album GD & TOP (2010). The album saw the release of three singles: "High High," "Oh Yeah," and "Knock Out," all of which have charted within the top three positions of the Gaon chart, with "High High" becoming a chart-topper.

Prior to his involvement with YG Entertainment, Seunghyun was an underground rapper and a childhood friend of G-Dragon, another member of Big Bang. G-Dragon stated that the two were "neighborhood friend[s] from middle school" and would often dance and rap together. Although G-Dragon later moved away and the two "became distant", he contacted Seunghyun again when YG Entertainment was scouting for candidates to create a boy band. The pair recorded several demos and sent them to Yang Hyun Suk, CEO of YG Entertainment, who later asked Seunghyun to audition. Seunghyun was initially rejected by the record label, which deemed him too "chubby" to fit the "idealistic version" of an idol. Seunghyun later stated that he "went home and exercised really hard because I wanted to join YG Entertainment." Six months later, he returned for another audition and was signed on. He reportedly lost 20 kg in 40 days.

Mansour Bahrami (Persian: منصور بهرامی‎) (born April 26, 1956) is a professional tennis player. He has held dual French and Iranian nationality since 1989.

From an early age he worked as a ball boy within a sports complex in Tehran, Iran. He observed many of the best Iranian tennis players in action but he was never allowed to play. Eventually he snuck onto one of the courts but his first racquet was destroyed by an outraged armed guard who kicked him out. He resorted to learning the game through the use of his hands or frying pans or broom handles. Bahrami has often commented that his outrageous shotmaking ability resulted from mastering tennis using such unusual implements.

The time came when the Iranian team was short of players and Bahrami was finally permitted to play the game on a tennis court. His talent was obvious and he reached the Davis Cup team (and helped the team to victory at the age of just sixteen) but in the late 1970s the Islamic Revolution within Iran led to tennis being viewed as a capitalist and elitist sport. He spent the next three years playing backgammon as all tennis courts were closed down. In desperation he fled to France with his life savings, which he gambled in a casino and lost. A number of friends supported him financially as he began to play a few tournaments within France.

Scott Joplin (ca. 1867/1868? – April 1, 1917) was an American composer and pianist. Joplin achieved fame for his ragtime compositions, and was later dubbed "The King of Ragtime". During his brief career, Joplin wrote 44 original ragtime pieces, one ragtime ballet, and two operas. One of his first pieces, the Maple Leaf Rag, became ragtime's first and most influential hit, and has been recognized as the archetypal rag.

Joplin was born into a musical African American family of laborers in Northeast Texas, and developed his musical knowledge with the help of local teachers, most notably Julius Weiss. Joplin grew up in Texarkana, where he formed a vocal quartet, and taught mandolin and guitar. During the late 1880s he left his job as a laborer with the railroad, and travelled around the American South as an itinerant musician. He went to Chicago for the World's Fair of 1893, which played a major part in making ragtime a national craze by 1897.

Joplin moved to Sedalia, Missouri in 1894, and earned a living teaching piano and going on tour across the Southern US. In Sedalia, he taught future ragtime composers Arthur Marshall, Scott Hayden and Brun Campbell. Joplin began publishing music in 1895, and publication of his Maple Leaf Rag in 1899 brought him fame and had a profound influence on subsequent writers of ragtime. It also brought the composer a steady income for life. During his lifetime, Joplin did not reach this level of success again and frequently had financial problems.

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.

Terius Youngdell Nash (Born September 20, 1977), better known by his stage name The-Dream, is an American singer-songwriter and record producer. He is known for co-writing chart topping hits such as "Baby" for Justin Bieber, "Umbrella" for Rihanna and "Single Ladies (Put a Ring on It)" for Beyoncé, as well as for his three solo albums, Love Hate, Love vs. Money, and Love King.

Terius Nash was born in Rockingham, North Carolina and moved with his mother, Reva Nash, to Atlanta at the age of 3. He played trumpet, drums, and guitar as a child. His mother died in 1992 when Nash was fifteen years old, an event which would inspire him to write songs. He states that the death of his mother gave him a "soft spot" for women, which he credits to his desire to write songs about female empowerment such as Rihanna's "Umbrella". He moved in with his grandfather, a concrete mason who instilled a strong work ethic in young Nash. Of his grandfather, Nash recalls "He came out of a bad time for blacks in the South, but even though we lived in the hood, we had a boat, some cars and a house that was paid for. So I’ve always had a different outlook on life. There’s nothing I can’t do."
