Many k-pop fans worldwide have their eyes on SM's latest girl group, and as of September 2, f(x) has officially stepped onto the girl group battlegrounds! This special date marked the hot quintet's first showcase, which took place in Seoul. These girls stepped out of nowhere a mere ten days ago, and already they've generated a strong fanbase. Even those who aren't fans yet are curious to see what this group has to offer after SM unmasked the group, unveiled solo shots of each member and released a MV teaser and the full Lachata track. The Samsung Exclusive event was full of eye candy and talent. Through the first live "Lachata" (or, as the official typography seems to, LA chA TA... don't ask) performance as well as the release of the full music video, f(x) undoubtedly delivered! SM Entertainment really went out on this one - they were smart to pull big-name idols, namely SNSD's Sunny and Super Junior's Leeteuk as MCs for the event. The highly anticipated showcase started with a bang - equipped with popular 2008 hits like Sam Sparro's track "Black & Gold" and Britney Spears' "Womanizer". Can we just say, majorly HOT? In addition to the support from well-known MC's, SNSD and SHINee have been reported as attending the showcase to help support f(x) as well. The guest list was limited to a lucky 150 people who were chosen from the internet. There has been no official word as of yet about the whether or not f(x) member Krystal's sister, SNSD's Jessica, attended or not. The reaction to the girls' revealed talents is already very hot and positive - many claim that, though f(x) has a powerful charm, the members exude a feminine beauty (sounds familiar...). The solo performances by Luna & Victoria have especially garnered attention from fans. f(x)'s maknae, Krystal, expressed the burden in preparing for such a debut. Though the youngest member of the fivesome, Krystal has gained quite a bit of attention with her roles in various CF's and also as Jessica's younger sister. Furthermore, the Chinese-American Amber has also caused a lot of buzz amongst netizens and curious k-pop fans both in Korea and on the international scape for her androgynous appearance; Amber undoubtedly gives off a vibe unconventional to the girl group scene. Even with so many groups out these past few months, Amber is the first to give such a masculine appearance. Even if she isn't actually a guy, Amber is already forming a fanbase with her unique appeal. Victoria, the leader and oldest of the five, also expressed about how she hoped to become a great and dependable leader for the group through hard work and dedication. So many fans have been wondering, what exactly does 'Lachata' refer to anyway? Because this song is about "enjoying life", this term is an interjection to give a fun, bright and cheerful atmosphere; furthermore, the syllables are easy to pronounce and remember. f(x)'s debut song is the latest work by hit songwriter Kenzie, known for his impressive arrangements of dance-pop and electronic songs. According to Kenzie, 'Lachata' is more than just a catchy tune; listeners will be fascinated by the upbeat melodies and witty lyrics that permeates throughout the track. This song surfaced the internet on September 1 and has since received an explosive reaction. f(x) hasn't even had their official debut stage yet, but many are eager to see this fresh face on the music scene; f(x) is already promising a distinctive color and talent to threaten the girl group scene!
