  f(x) officially debuted in September 2009 with the release of the digital single "La Cha Ta". Their debut studio album, Pinocchio, and their two extended plays Nu Abo and Electric Shock produced three number one singles on South Korea's Gaon Digital Chart. Their acclaimed second studio album, Pink Tape, was the only K-pop album on US music channel Fuse's "41 Best Albums of 2013" and was named "Greatest K-pop Album of the 2010s" by Billboard. The group's third and fourth albums, Red Light and 4 Walls, were commercially successful and well-received by music critics. After releasing the SM Station single "All Mine" in 2016, the group halted group promotions and the members have embarked on individual music, acting, and modelling careers. In August 2019, f(x) officially reunited as a three-piece and performed at the three-night SM Town Live 2019 in Tokyo concert.
