Question:
The Spice Girls are an English pop girl group formed in 1994. The group originally consisted of Melanie Brown ("Scary Spice"), Melanie Chisholm ("Sporty Spice"), Emma Bunton ("Baby Spice"), Geri Halliwell ("Ginger Spice"), and Victoria Beckham, nee Adams ("Posh Spice"). They were signed to Virgin Records and released their debut single "Wannabe" in 1996, which hit number one in 37 countries and established them as a global phenomenon. Their debut album Spice sold more than 31 million copies worldwide, becoming the best-selling album by a female group in history.
While on tour in the United-States, the group continued to record new material and released a new song, "Goodbye", before Christmas in 1998. The song was seen as a tribute to Geri Halliwell, and when it topped the UK Singles Chart it became their third consecutive Christmas number-one - equalling the record previously set by the Beatles. Later in 1998, Bunton and Chisholm appeared at the 1998 MTV Europe Music Awards without their other band members, and the group won two awards: "Best Pop Act" and "Best Group" for a second time. In late 1998, Brown and Adams announced they were both pregnant; Brown was married to dancer Jimmy Gulzer and became known as Mel G for a brief period. She gave birth to daughter Phoenix Chi in February 1999. One month later, Adams gave birth to son Brooklyn, whose father was then Manchester United footballer David Beckham. Later that year, she married Beckham in a highly publicised wedding in Ireland. The Spice Girls returned to the studio in August 1999, after an eight-month recording break to start work on their third and last studio album. The album's sound was initially more pop-influenced, similar to their first two albums, and included production from Eliot Kennedy. The album's sound took a mature direction when American producers like Rodney Jerkins, Jimmy Jam and Terry Lewis came on to collaborate with the group. In December 1999 they performed live for a UK-only tour, Christmas in Spiceworld, in London and Manchester, also showcasing new songs from the third album. During 1999, the group recorded the character Amneris' song "My Strongest Suit" in Elton John and Tim Rice's Aida, a concept album which would later go on to fuel the musical version of Verdi's Aida. The band performed again at the 2000 Brit Awards, where they received a Lifetime Achievement Award. Despite being at the event, Halliwell did not join her former bandmates on stage. In November 2000, the group released Forever. Sporting a new edgier R&B sound, the album received a lukewarm response from critics. In the US, the album peaked at number thirty-nine on the Billboard 200 albums chart. In the UK, the album was released the same week as Westlife's Coast to Coast album and the chart battle was widely reported by the media, where Westlife won the battle reaching number one in the UK, leaving the Spice Girls at number two. The lead single from Forever, the double A-side "Holler"/"Let Love Lead the Way", became the group's ninth number one single in the UK. However the song failed to break onto the Billboard Hot 100 singles chart stateside, instead peaking at number seven on the Bubbling Under Hot 100 Singles. "Holler" did peak at number thirty-one on the Hot Dance Music/Club Play chart in 2000. The only major performance of the lead single came at the MTV Europe Music Awards on 16 November 2000. In total, Forever achieved only a fraction of the success of its two best-selling predecessors, selling five million copies. In December 2000, the group unofficially announced that they were beginning an indefinite hiatus and would be concentrating on their solo careers in regards to their foreseeable future, although they pointed out that the group was not splitting.

Question:
Williams was born on April 5, 1973, in Virginia Beach, Virginia, the oldest of three sons of Pharaoh Williams, a handyman, and his wife Carolyn, a teacher. His roots extend for generations in Virginia and North Carolina, and one of his ancestors journeyed to West Africa in 1831, prompting other relatives to emigrate from America to Liberia in 1832. He met Chad Hugo in a seventh-grade summer band camp where Williams played the keyboards and drums and Hugo played tenor saxophone. They were also both members of a marching band; Williams played the snare drum while Hugo was drum major.
On March 31, 2014, Williams was announced as a new coach for the seventh season of The Voice, replacing CeeLo Green. On May 18, 2015, Team Pharrell had 16-year-old Sawyer Fredericks win the eighth season of The Voice. In June 2014, it was announced that Williams would make a guest appearance on the docu-series Sisterhood of Hip Hop. Williams was the executive producer of Atlanta rapper T.I.'s ninth studio album, Paperwork, which was released on October 21, 2014 by Grand Hustle and Columbia Records. In May 2014, Williams curated an art show named after his album, "Girl," at the Galerie Perrotin in Paris, France. The show included 37 artists including Takashi Murakami, JR, Daniel Arsham, and Marina Abramovic among others." Comme des Garcons developed a unisex fragrance with Williams scheduled for release in late 2014. Kaws designed the bottle artwork. In January 2015, Williams and Al Gore announced that they are teaming up to create a 7-continent "Live Earth" concert on June 18 to raise awareness about and pressure governments to act on climate change.

Williams recorded three songs for the soundtrack to the animated film The SpongeBob Movie: Sponge Out of Water. He also recorded a song "Shine" with Gwen Stefani for the Paddington movie. At the 2015 Grammy Awards Williams performed an orchestral rendition of "Happy" with composer Hans Zimmer and pianist Lang Lang that included a tribute to the Black Lives Matter "Hands Up, Don't Shoot" movement inspired by Eric Garner's death and the events in Ferguson, Missouri. In 2015, a unanimous jury determined that Williams's 2013 hit song "Blurred Lines" was an infringement of the 1977 Marvin Gaye song "Got to Give It Up". The jury awarded the Gaye family $7.4 million in damages for the copyright infringement based on profits generated. In October 2015, the Tisch School of the Arts at New York University named Williams as their artist-in-residence. He gave the 2017 commencement address at NYU and received an honorary degree on May 17, 2017. Also in October 2015, Williams announced that he will perform with a gospel choir on Sunday, November 1, at Emanuel AME Church in Charleston, South Carolina, where nine black parishioners were shot and killed on June 17, allegedly by a young white man who is awaiting trial. This is part of a program on race relations being produced by A+E Networks and iHeartMedia. Williams plans to speak with community leaders and others affected by the shooting, which dominated the U.S. news media for several days. The two-hour Shining a Light: A Concert for Progress on Race in America program is scheduled to air November 20, and will also feature a concert to be filmed November 18 in Los Angeles. A goal of the program is to raise money for the victims of racial violence and for organizations around the country working to promote racial equity.
