It is her first studio album since "Trip the Light Fantastic" (2007).
Document 2: Mixed Up World: "Mixed Up World" is a song by British singer-songwriter Sophie Ellis-Bextor, released in 2003 as the first single from her second studio album, "Shoot from the Hip". It peaked at #7 on the UK Singles Chart. It was considered somewhat of a success. The single includes an easy-listening, chillout B-side, called "The Earth Shook the Devil's Hand". The video for the song features various dancers wearing a mix of bright and dark colours. It also features men in bowler hats as Sophie moves between giant black and white punctuation marks. It was directed by Rupert Jones. It was the first video that shows Sophie's blonde hairstyle. A short clip from the video was featured in an ad on Australia's VH1 channel in June 2006. "Mixed Up World" sold 35,000 copies in the United Kingdom.
Document 3: Beyoncé: Her debut single, "Crazy in Love" was named VH1's "Greatest Song of the 2000s", NME's "Best Track of the 00s" and "Pop Song of the Century", considered by Rolling Stone to be one of the 500 greatest songs of all time, earned two Grammy Awards and is one of the best-selling singles of all time at around 8 million copies. The music video for "Single Ladies (Put a Ring on It)", which achieved fame for its intricate choreography and its deployment of jazz hands, was credited by the Toronto Star as having started the "first major dance craze of both the new millennium and the Internet", triggering a number of parodies of the dance choreography and a legion of amateur imitators on YouTube. In 2013, Drake released a single titled "Girls Love Beyoncé", which featured an interpolation from Destiny Child's "Say My Name" and discussed his relationship with women. In January 2012, research scientist Bryan Lessard named Scaptia beyonceae, a species of horse fly found in Northern Queensland, Australia after Beyoncé due to the fly's unique golden hairs on its abdomen. In July 2014, a Beyoncé exhibit was introduced into the "Legends of Rock" section of the Rock and Roll Hall of Fame. The black leotard from the "Single Ladies" video and her outfit from the Super Bowl half time performance are among several pieces housed at the museum.
Document 4: Sophie Ellis-Bextor: Ellis-Bextor was born in London to Janet Ellis, who was later a presenter on BBC's children's television programmes "Blue Peter" and "Jigsaw", and Robin Bextor, a film producer and director: they separated when she was four. As a child, Ellis-Bextor occasionally appeared on "Blue Peter" alongside her mother, who presented the programme.
Document 5: Video Killed the Radio Star: The music video for ``Video Killed the Radio Star '', written, directed and edited by Australian Russell Mulcahy, was produced on a budget of $50,000. It was filmed in only a day in South London, and was edited in a couple of days. Mulcahy asked Virginia Hey, a friend who was a model and aspiring actress, to dress`` in a silver costume and be lowered via wires in a test tube.'' There were about 30 takes required for shots of the actress in the tube. The tube falls over in the video, although Mulcahy claims it was not intended to be shown in the final edit. Hans Zimmer can be briefly seen wearing black playing a keyboard, and Debi Doss and Linda Jardim, who provided the female vocals for the song, are also seen.

Document 8: Suga Mama: The accompanying music video for "Suga Mama" was released to British music channels in April 2007. It was shot in black-and-white and was co-directed by Melina Matsoukas alongside Knowles for the B'Day Anthology Video Album, which was released the same month; "Suga Mama" was one of eight videos shot in two weeks for the video album. It begins with Knowles sitting in a chair, wearing men's clothing and smoking a cigar. She gets up and begins to pole dance. The remainder of the video presents Knowles dancing on top of a sugar cube, dancing with backing dancers whose faces are partially concealed, lying in a circle of light, and riding a mechanical bull. Knowles said she is meant to "slowly become a woman" during the video, adding "Well, a sexier woman – I'm always a woman."Knowles rehearsed the pole dancing using two ballet bars, which was when it was decided to add a pole above her head to form an arc. Though she is from Texas, she had never previously been on mechanical bull. There were no problems during warm-ups, but the man operating the bull during the video shoot programmed it to go faster, causing Knowles to fall off when she tried to perform tricks such as lifting up her foot, leaning back and turning around. To minimize the time Knowles spent on the bull, the director shot the sequence at twelve frames per second (see frame rate) and Knowles sang twice as quickly, but it wasn't until 4:00 am that they completed work.
