Big Bang
( 빅뱅) is a Korean hip hop & R&B group composed of five members, each contributing different vocal or rapping parts. They are considered to be the new face of the YG Family.Debuting in 2006, they quickly became popular, and experienced great success in 2007 with the release of their single "Lies", shooting the five-member boy band into super stardom as one of the biggest boy bands in Korea alongside the female group Wonder Girls. Big Bang have been noted for their music as well as their taste in fashion, becoming famous throughout the country in the process

Pre-debute
Before Big Bang debuted, each member had his own degree of success and popularity in the entertainment industry. G-Dragon and Tae Yang have been with YG Entertainment since they were both twelve years old, both known as GDYB back than (as Tae Yang's real name is Young Bae). T.O.P was well known as an underground hip-hop rapper while Seung-ri was first introduced to the entertainment industry through the show Let's Coke Play Battle Shinhwa!.The only one who perhaps was not known before the debut of Big Bang was Daesung.
In Summer 2006, M-net released an eleven episode documentary that showed the members in training before their debut as a group. The first six episodes detailed each individual member's background and motivation for becoming a singer. The documentary portrayed the arduous process of training by showing their dancing and singing practice sessions. Beyond being just an entertaining television show, it was an actual elimination process of candidates unfit for debut. Two members, SO-1 and Seungri (Lee SeungHyun) were considered for elimination, but they were given second chances to showcase their abilities in singing, dancing, and performing. Yet this resulted in Yang Hyun Suk (CEO of YG Entertainment)dropping SO-1 because he lacked stage presence and was "too shy". On the other hand, Seungri was able to successfully impress Yang Hyun Suk with his dancing and singing skills; thus, making the group. This documentary made the group members even more popular before their debut in the Korean entertainment industry as Big Bang.
While many boy bands at the time were typically marketed as "cute" singers, the producer of YG Entertainment wanted a band to eclipse the popularity of "cute" singers and have a boy band that could "actually sing." Before debuting as "Big Bang", the members suggested various names, such as "Apex", "Stump," and "Diamond".

Note;
Hip-hop sensation BIG BANG returns with new music just in time for their anniversary. This album consists of a fresh style, but still has the Big Bang touch. The title song, 거짓말 (Lies), is a catchy house-style number written and composed by YG's prodigy, Big Bang's own G-Dragon. Another title track, Always, is written by 1TYM's Teddy, which captures listeners with sad lyrics and a nostalgic melody. The intro song is a bit different from the ones in their previous singles as this one showcases certain members' vocals. Also, 없는 번호 (No Number) has a somewhat catchy tune and is certainly worth a try. TOP impresses us with an immensely better solo than his previous, featuring new YG artiste Ji Eun. And finally, Oh Ma Baby is touching song with equally touching lyrics.
Although having debuted for only a little over a year, Big Bang is a group to be on the lookout for. They have shown that they are able to adapt well to different styles, as seen by their recent success in the charts and shows.
