Background and career
Rosa Isabel Mutya Buena ( muu-TEE-yə; born 21 May 1985) is a British singer and songwriter who rose to fame as a member of girl group Sugababes. With the Sugababes, Buena had four UK number-one singles, an additional six top-ten hits and three multi-platinum albums. After leaving the group in December 2005, she embarked on a solo career, releasing her debut solo album Real Girl in June 2007 under Island Records. The album spawned three top-twenty hits on the UK singles chart; the title track which reached number two, "Song 4 Mutya (Out of Control)" (with Groove Armada) which reached number eight, and "This Is Not Real Love" (with George Michael) reaching number fifteen. Real Girl entered the top ten on the UK Albums Chart and was certified Gold by the British Phonograhic Industry (BPI). Following the underperformance of the album's final two singles, "Just a Little Bit" and "B Boy Baby", Buena parted ways with Island Records in 2008. She subsequently collaborated with various independent artists including Ashley Walters, Don-E, Gak Jonze, and Coree Richards of Damage. In 2011, Buena reunited with her former Sugababes bandmates Siobhán Donaghy and Keisha Buchanan. The original trio opted to release music under the name MKS (Mutya Keisha Siobhan). Their first single, "Flatline", was released in 2013 under Polydor Records, to moderate commercial success. The group embarked on an indefinite hiatus the following year. In September 2019, the trio officially confirmed their return as Sugababes, after regaining the rights to use the name. Buena, as part of the Sugababes, was featured on the DJ Spoony track "Flowers" that year. In 2020, the group once again embarked on a temporary hiatus due to the COVID-19 pandemic, before returning in 2022. In February 2020, Buena collaborated with London-based production duo Electric Pineapple on the pop track entitled "Black Valentine", which was followed by the UK garage-inspired track "The One" with electronic music-producer duo Ryuken in May 2021. In April 2023, Buena was featured on the electro-house track "All I Own" by Dutch-Filipino DJ Laidback Luke. Buena has widely been praised as one of the best British voices of her generation, with The Guardian ranking her second on their 2019 list of the best girl-band members of all time.
Rosa Isabel Mutya Buena was born on 21 May 1985 in Kingsbury to a Filipino father and an Irish mother. She has four older brothers, one younger brother, and three younger sisters. Buena has described her household growing up as being very musical, and she often sang with her father who played guitar. At age six, Buena entered the Little Miss Philippines pageant in London, where she first sang in front of an audience, and earned the runner-up prize. Following this, she began performing at various events in the Philippine community, including at weddings, funerals, and birthday parties. In 1994, Buena appeared on an episode of Barrymore, where she sang "The Greatest Love of All" by Whitney Houston. On weekends, Buena attended a Filipino performing arts school called Euro-Fil. From the age of nine, she began touring Europe with a Filipino group called Pippa, where they would perform various traditional Filipino dances including tinikling and pandanggo. Buena has stated that she frequently sang songs by Whitney Houston and Barbra Streisand during her childhood, as well as Filipino songs including "Dahil sa Iyo" (1938), and "Matud Nila" (1941). She later attended Kingsbury High School with her fellow Sugababes band-mate Keisha Buchanan.
In 1998, at age 13, Buena, along with Keisha Buchanan and Siobhán Donaghy, began performing at showcases for music industry executives. That same year, the trio formed the girl group Sugababes, and signed to London Records. They were managed by Ron Tom, who had previously managed the British girl group All Saints. The group's BRIT-nominated debut single, "Overload", was released on 11 September 2000, and reached the top ten on the UK singles chart, while their debut album, One Touch, was released in November 2000. The album spawned three further UK top-forty singles, "New Year", "Run for Cover", and "Soul Sound", however sales of the album did not meet the expectations of London Records and the group were subsequently dropped. Donaghy left the group in 2001, after which Heidi Range replaced her and the group signed to Island Records. Buena achieved three multi-platinum albums with Sugababes under Island Records, including Angels with Dirty Faces (2002), Three (2003), and Taller in More Ways (2005), and four number one singles including "Freak Like Me", "Round Round", "Hole in the Head", and "Push the Button". On Three, Buena sang a primarily solo track titled "Maya", which is dedicated to her late sister who passed away during infancy. At the Brit Awards 2003, she won the award for Best British Dance Act as part of the group. Following the release of two singles from Taller in More Ways, "Push the Button" and "Ugly", Buena decided to leave the Sugababes in December 2005. She later attributed her struggle with postnatal depression following the birth of her daughter, the group's increasingly hectic schedule, and her desire to spend more time with her daughter as reasons for her departure. In retrospective interviews, Buena revealed that if she had been allowed a one month break from the group after the birth of her daughter, she may have stayed. The last remaining original member, Keisha Buchanan, said upon Buena's departure, "...we will all miss Mutya, but we also knew there was still a place for bringing in somebody new who could help us carry on taking the Sugababes brand of music forward".
According to Buena, following her departure from the Sugababes, she initially resisted recording solo music as she was worried that fans would believe this was the only reason she left the group. However, she ultimately chose to pursue a solo career, feeling that it would give her greater control over her sound and artistic direction, while allowing her to express aspects of her artistry that she felt unable to fully explore in the Sugababes. Her first release was a ballad duet with George Michael, titled "This Is Not Real Love", from Michael's greatest hits album Twenty Five (2006). Michael had previously wanted to work with Buena while she was still in the Sugababes, however the collaboration did not come to fruition at the time due to scheduling conflicts and Island Record's reluctance to let Buena record solo music outside of the group. Upon Buena leaving Sugababes, Michael once again contacted her and asked if she would still like to work with him, after which she agreed and they began studio sessions for the song. It was ultimately released in November 2006, and reached number fifteen in the United Kingdom, while peaking in the top ten in Italy and Denmark. Her debut solo single, "Real Girl", followed in May 2007. The track samples Lenny Kravitz's song "It Ain't Over 'Til It's Over", and was produced by London-based production company Full Phat, consisting of Matt Ward and Dean Gillard. It reached number two in the United Kingdom, and was shortlisted for Best British Single at the Brit Awards 2008. "Real Girl" was also featured on the Sex and the City, Vol 2: More Music Soundtrack (2008). Buena's debut album, Real Girl, was released on 4 June 2007 through Island Records, and peaked at number ten on the UK Albums Chart. The following month, her collaboration with Groove Armada, "Song 4 Mutya (Out of Control)", was released. The song is featured on their album Soundboy Rock (2007), and serves as the third single from Real Girl. It peaked at number eight on the UK singles chart, and spent seven weeks in the top forty. The fourth release from Real Girl, "Just a Little Bit", reached number sixty-five in the United Kingdom, while the fifth and final single "B Boy Baby", a re-working of the track "Be My Baby" by the Ronettes and featuring Amy Winehouse, reached number seventy-three. Buena was nominated for the "Best Newcomer" award at the 2007 MOBO Awards, which took place on 19 September 2007. In December 2007, Real Girl was certified gold by the British Phonographic Industry (BPI), denoting sales of 100,000 copies in the country. Despite this, in February 2008, Buena was dropped by Island Records due to the poor charting positions of her last two singles from Real Girl, "Just a Little Bit" and "B Boy Baby". In October 2008, Buena appeared on Alan Carr's Celebrity Ding Dong.
On 2 January 2009, Buena entered Celebrity Big Brother 6 as a housemate. On 16 January 2009, day 15 of the series, she walked out of the Big Brother house after surviving eviction the same night, stating that she missed her daughter. That same year, Buena began collaborating with various independent artists, including Ashley Walters' on the single "With You", from his album Ashley Walters, the Don-E track "The Time Is Now", "Fallin" with Agent X, and "Give Back" with Tah Mac. Buena joined an array of artists to feature on the debut single of the London-based production duo NightShift, titled "Can You Persuade Me", a remix of "I Know You Want Me (Calle Ocho)" (2009) by Pitbull. In March 2010, Buena filed a claim for ownership of the Sugababes name with the European Trademark Authority, following Buchanan's departure from the group in September 2009. Though Buchanan and Donaghy's names appear on the trademark submission, it was confirmed that Buena was the sole applicant for submission and Donaghy and Buchanan were not involved. The fourth line-up launched an opposition to the claim on the basis that goodwill and reputation in the mark and trading name "Sugababes" belongs to the partnership – not an individual. In September 2010, Buena contributed six tracks to the compilation album The Sound of Camden. She recorded a series of covers of rock songs from rock bands such as U2, the Pixies and Iron Maiden. The album was made available on iTunes and sold at Camden Market in London. In October, Buena expressed uncertainty about continuing in the music industry and said she was currently training to become a psychologist for children. Despite the announcement, Buena teamed up with City Boy Soul, a band consisting of ex-Damage singer Coree Richards and British rapper Gak Jonze, and digitally released "Be Ok" in January 2011. Buena also recorded lead vocals for "Give Me Love", by the British DJ and producer Paul Morrell. On 28 May 2011, Buena performed at Birmingham Gay Pride. In December 2011, a video blog posted by The Sabotages Studio revealed that Buena was set to release "My Love" featuring Thor Alaye in early 2012, and "Bedroom" featuring Shide Boss that same year.
In October 2011, several news outlets reported that the original line-up of the Sugababes would reform. In January 2012, both Buena and Buchanan tweeted they were in the studio with "two other females" and British rapper Professor Green. However, Buena later contrasted this on Twitter, saying: "No track with Keisha or Professor G, he was around the studio. I'm just working on my stuff at the moment [sic]". Scottish singer-songwriter Emeli Sandé confirmed to MTV UK that she had written new songs for Buena, Buchanan and Donaghy, saying: "Yes, that is true. I've written for the original line-up of the Sugababes [sic], which I'm very happy about because I just loved them when they first came out. I loved their sound, it was so cool. It was very different, so I'm happy to kind of be involved in what started the whole Sugababes journey. It sounds amazing". In April 2012, it was reported that the line-up had signed a £1 million record deal with Polydor Records. In July 2012, it was officially confirmed the group had reformed under the name Mutya Keisha Siobhan and were writing songs for a new album under Polydor. The group appeared on the cover of fashion magazine Ponystep in December 2012. That same month, they performed an intimate gig at Ponystep's New Year's Eve party. The performance marked the first time Buena, Buchanan and Donaghy had performed together in over a decade. On 26 March 2013, the group featured on a remix of Phoenix's single "Entertainment". Mutya Keisha Siobhan's first single, "Flatline", was released in June 2013. The track experienced moderate commercial success, peaking at number 50 in the UK. MKS performed their first official headlining gig at Scala on 1 August. On 6 November 2013, Buena said that she was open to reclaiming the Sugababes name. In November 2013, the group embarked on the Sacred Three Tour, playing six dates across the UK. In February 2014, Buena attended the NME Awards 2014 as part of Mutya Keisha Siobhan, where the trio performed with English electronic music band Metronomy. On 13 February 2015, the group released the single "Back in the Day".
