() was a South Korean music group active from 1992 to 1996. The three members of the boy band, Seo Taiji, Yang Hyun-suk and Lee Juno, experimented with many different genres of popular Western music. Seo Taiji and Boys was highly successful and is credited with changing the South Korean music industry by pioneering the use of rap in Korean popular music and utilizing social critique, despite pressure from ethics and censorship committees. The band won the Grand Prize at the Seoul Music Awards in both 1992 and 1993. In April 1996, Billboard reported that the band's first three albums had each sold over 1.6 million copies, with the fourth nearing two million, making all four some of the best-selling albums in South Korea. History After the breakup of the heavy metal band Sinawe in 1991, Seo Taiji switched gears and formed the group Seo Taiji and Boys with dancers and backing vocalists Yang Hyun-suk and Lee Juno. Yang said he first met Seo when the musician came to him to learn how to dance. "Blown away" by his music, Yang offered to join the group, and they later recruited Lee who was one of the top dancers in Korea and joined the group as a background dancer, despite being highly regarded in his own right, because the music "moved [his] heart." Seo Taiji came across MIDI technology for the first time in South Korea in the early 1990s and started experimenting with different MIDI sounds to create a new type of music that had not been heard by the public. He initially had no plans to debut as a dance/pop boy group, and Seo Taiji and Boys' mainstream success was a surprise. 1992: "I Know" The trio debuted on MBC's talent show on April 11, 1992, with their song "Nan Arayo" (난 알아요, "I Know") and got the lowest rating from the jury. However, the song and their self-titled debut album became so successful that, according to MTV Iggy, "K-pop" music would never be the same" again. One of the first Korean rap songs, "Nan Arayo" was a hugely successful hit; its new jack swing-inspired beats, upbeat rap verses and pop-style choruses combined with a focus on new dance moves took Korean audiences by storm. Influenced by the videos for Technotronic's "Pump Up the Jam" and Snap!'s "The Power", the music video for "Nan Arayo" features varying color saturation
