f(x) (/ˌɛf ˈɛks/; Hangul: 에프엑스) is a South Korea-based girl group formed by S.M. Entertainment in 2009. Since their debut, f(x) has released four full-length albums, two extended plays, and one repackaged album. The group is composed of four members: Victoria, Amber, Luna, and Krystal.

f(x) has been recognised for their experimental style and eclectic, electropop-based sound.[1] They are one of the more recognized K-pop groups internationally,[2] becoming the first K-pop act to perform at SXSW.[3] Their acclaimed second album, Pink Tape, was the only K-pop album on US music channel Fuse's '41 Best Albums of 2013'.[4]



Krystal was scouted by S.M. Entertainment in 2000 while on a family visit to Korea, along with her sister Jessica (now a former member of Girls' Generation). She subsequently appeared in a small role in Shinhwa's music video for the song "Wedding March" ("너의 곁에서 2").[5][6]

Former member Sulli was a child actress, making her first television appearance in 2005 as the young Princess Seonhwa of Silla in SBS's Ballad of Seodong.[7]

Luna was recruited by S.M. Entertainment following her 2006 appearance on the reality television programme Truth Game.[8]

Victoria was scouted through a Beijing dance competition in September 2007.

Two months later, Amber was cast through S.M. Global Auditions in Los Angeles, California.

2009–2010: Debut and Nu ABO[edit]

f(x) was first introduced as a five-member dance-focused pop group in a teaser clip released on August 24, 2009. Their debut single "LA chA TA" was released on September 1, with a showcase held the following day at Samseong Fashion Center in Gangnam. The group's broadcast debut was on September 5, on MBC's Music Core.

A month later, the group appeared as special guests at Girls' Generation's Into The New World concert at the Olympic Fencing Gymnasium, Seoul.

At the start of 2010, f(x) collaborated with the Chinese boy band M.I.C. to promote the LG Cyon cell phone, releasing a Chinese cover of "Lollipop". In April they appeared in their documentary reality programme, Hello f(x). On May 4, the group released their first extended play, Nu ABO. The lead single "Nu ABO" was a commercial success in Korea and become a number-one single on the Gaon Chart.

They promoted the single "Mr Boogie" as a follow-up single from their EP and participated in the SMTown Live '10 World Tour, as well as filming their second documentary reality show, f(x)'s Koala. Towards the end of 2010 it was announced that f(x)'s albums would be distributed under Japanese label Avex Entertainment in Japan, Taiwan, China, and Hong Kong. Amber returned to the group in early 2011.

2011–2012: Pinocchio, Hot Summer, and Electric Shock[edit]

f(x) released their first full-length studio album Pinocchio in April 2011, with the lead single "Pinocchio (Danger)". The single peaked at number one on the Gaon digital single chart, and the group went on to take eight music show wins.

The repackaged album contained the title track "Hot Summer" (a remake of a Monrose song produced by Thomas Troelsen and Remee), as well as three previously released digital singles: "LA chA TA", "Chu~♡", and "Is It Ok?".[9] "Hot Summer" peaked at #2 on the Gaon digital single chart and was downloaded over 375,000 times in the week of release.
