4Sisters (stylized in all caps; formerly known as 4th Impact) is a Filipino girl group composed of sisters Almira, Irene, Mylene and Celina Cercado. The group competed in the twelfth season of the British singing contest The X Factor, where they were the ninth contestant eliminated. They are also known for having participated in several Philippine and international talent competitions, including the World Championships of Performing Arts, which they won in 2006 and 2013, and the South Korean talent search Superstar K6 in 2014, where they reached eighth place. The sisters are originally from Roxas, Isabela, and are now based in Metro Manila.

Career 2001–2014: Early years Almira, the eldest of the sisters in the group, first began competing at a young age in Filipino talent shows such as Batang Kampeon, which was won by Charice Pempengco, and Star for a Night, which was won by Sarah Geronimo.

The group was formed in 2001 at the suggestion of an aunt. Initially, they named themselves 'The Cercado Sisters' after their surname and began performing and competing as a girl group at festivals, events and talent shows in Roxas, Isabela. In 2006, they were approached by one of the producers of the talent show FamJam, who asked them if they would like to represent the Philippines in the World Championships of Performing Arts. They elected to join and eventually won 16 gold medals and four outstanding plaques and were proclaimed Junior Vocal Group Grand Champion of the competition. The following year, the group was invited to perform in the 2007 Monaco Charity Film Festival. In 2008, the group released a six-track self-titled EP under Viva Records, which did not reach commercial success. In 2009, they also began using the name 'The Gollayan Sisters', which was derived from their middle name. They continued to compete in various singing contests and in 2012 participated as members of a family troupe that won in the Filipino variety show It's Showtime, singing covers of "I Believe I Can Fly" and "Queen of the Night". Early in 2013, the group landed a regular gig in the musical variety show Sarah G Live as backup singers and dancers. Later that same year, the group competed and won again in the World Championships of Performing Arts, this time as the Grand Winner in the Senior Vocal Group Category, bringing home 20 gold medals, four silver medals and four overall champion plaques. In April 2014, the group released their album The Cercados: Unstoppable! under Saturno Music, which also failed to reach commercial success.

2014: Superstar K

In August 2014, the group traveled to South Korea to audition in the talent competition Superstar K6. The competition organizers asked if they could change their group name to something more easily remembered and pronounced, which caused their name to be changed to 'MICA', an acronym formed from the first letters of their names. Their performance impressed the judges and the group moved on to the next round, where they performed their rendition of Idina Menzel's song "Let It Go" from the Disney movie Frozen. Their performance went viral on social media and YouTube, quickly garnering over 20 million views in a short period of time. After competing in the knock-out stages of the show, MICA was eliminated in the second round of "Super Week". The judges, however, decided to bring them back as a wildcard act, and the group, along with 10 other acts, progressed to the live show stage of the competition. At that point, they were the only non-native Korean-speaking contestants remaining on the show. The group was eliminated in Week 3 of the competition, finishing in eighth place.

2015: The X Factor

After their experience in Superstar K6, the group was planning to abandon their singing career until a fan from the United Kingdom suggested auditioning for the British singing contest The X Factor. The group decided to submit an online application for the aforementioned reality TV competition, and, after a few months, received an invitation to audition for the show. In July 2015, the sisters traveled to London, and after going through several screening tryouts, eventually made it to the arena auditions for the 12th season of The X Factor. Because there was already a current British artist named MICA, they introduced themselves as 4th Power and performed "Bang Bang" by Jessie J, Ariana Grande and Nicki Minaj as their audition piece. Their performance received a standing ovation from the audience and all four judges, with Simon Cowell saying, "In terms of first auditions, this is probably one of the best I've ever seen." After its airing, the group's audition went viral on YouTube and Facebook; and, as of June 2022, their YouTube audition video has garnered over 185 million views and is currently the most watched video in the show's history while the same video in Facebook has over 366 million views. The group sailed through the "Boot Camp" rounds of the show, where they performed "Proud Mary" by Tina Turner and "Titanium" by David Guetta, and the "Six-Chair Challenge" round where they performed "Show Me How You Burlesque" by Christina Aguilera. There, the mentor for group acts, Cheryl Fernandez-Versini, selected them as one of her final six acts. At this time, copyright issues were raised regarding their use of the name 4th Power, forcing the group to re-brand themselves again as 4th Impact. They then progressed to the "Judge's Houses" round, where they sang "Love the Way You Lie (Part II)" by Rihanna ft Eminem and were selected to move on to the live shows.

In the show's quarter-final, the group ended up ranking in the bottom two of the contestants remaining. Being one of the two acts who received the fewest public votes, they had to perform against fellow contestant Lauren Murray for the last slot in the semi-final. For the sing-off, the group performed Jennifer Hudson's rendition of "And I Am Telling You I'm Not Going" by Jennifer Holliday. Show judges Rita Ora and Nick Grimshaw voted to send Murray through to the semi-final while Cheryl Fernandez-Versini and Simon Cowell voted to send 4th Impact through to the semi-final. The result went into a deadlock and Lauren Murray, who had more public votes compared to 4th Impact, advanced to the semi-final which meant the group been the twelfth contestant eliminated. .

They appeared in several shows, venues and events in London and nearby cities. In early 2016, the group traveled on their first official tour, The X Factor Live Tour, co-headlining with Louisa Johnson, Reggie 'n' Bollie, Che Chesterman, Lauren Murray, Anton Stephans, Mason Noise and Seann Miley Moore. Polls conducted by the show's producers prior to the tour showed 4th Impact as the most anticipated act in the tour's lineup.
