Big Bang is a Korean hip hop group composed of five members. Although all members are involved in promotion, they do not sing all parts of each song as one; certain members are vocalists, while others are rappers. They are considered to be the new face of YG Family.

Big Bang made its debut at the YG Family concert, held on August 19th, 2006 at the Gymnastics Arena in Seoul Olympic Park. It originally consisted of six members, but one was dropped in the ninth episode of their documentary episodes. Big Bang released its first single, "The First Single Album," on August 29, 2006 with the song "This Love" getting high requests among radio stations. Their second single "Big Bang is V.I.P." was released a month later on September 28, 2006. On November 22, 2006 they released their third single entitled "B I G B A N G 0 3". The following month, their first album "Since 2007" was released, with a total of 48,009 copies sold.
