Tablo

Context: Tablo met Mithra Jin and DJ Tukutz in the underground hip-hop scene. They formed Epik High and under the tutelage of Movement crew members, especially CB Mass (currently Dynamic Duo), they attempted to record their first record alongside hip-hop duo, and close friends, TBNY (composed of Yankie and TopBob). However, CB Mass member Curbin allegedly embezzled Epik High and TBNY's funds for their first studio album, effectively causing the disbandment of CB Mass (and the creation of Dynamic Duo without Curbin). Tablo and Epik High were finally signed by Woolim Entertainment, which at the time focused on underground hip hop and modern rock. Tablo made his official debut as the leader of the group Epik High in 2003 alongside DJ Tukutz and Mithra Jin. The group's first album, Map of the Human Soul, was released on October 21, 2003. However, due to hip hop's lack of popularity in South Korea at the time, the album was a commercial failure. It wasn't until the release of their second album, High Society, that the group started to become more popular. Epik High's third album, Swan Songs, was originally intended to be their last album; however, upon release, the album became number one on numerous charts, and swept the year-end hip hop awards. One of the lead singles from the album, "Fly", was featured on the soundtrack of the video game FIFA 07. Due to the numerous offers to remake "Fly", as well as "Paris", the second single from the album, a CD sampler, was released in Japan. In 2007, the group released their fourth studio album, Remapping the Human Soul, and managed to push Epik High to the number one spot for best upcoming artist after selling almost 90,000 copies in the first month of release. The album ended up becoming South Korea's third best-selling album of 2007. However, many songs from the album were banned from several channels and the album buying age was restricted to 19+ due to some songs dealing with issues the Ministry of Culture and Tourism in South Korea deemed inappropriate for younger listeners. The group later went on to release their next album, Pieces, Part One, which was also a commercial success. In late 2008, Tablo published a book entitled Pieces of You. Although the stories were originally written in English, the book was first published in Korean. The Korean translation sold 50,000 copies in its first week of release and topped the bestseller's list in Korea. The original English version was released in February 2009 and also met with moderate success. The book garned a positive reception from critics, with Tablo's writing praised for a first-time author. After the group's contract with Woolim Entertainment expired in 2008, Tablo, alongside his group members, founded their own independent label, Map the Soul, and they went on to release an album of the same name. Through their independent label, the group went on to release two more albums; [e] in 2009, and Epilogue in 2010. In November 2013, Tablo revealed the reason of shutting down the label "Map the Soul" in his interview with HiphopLE that one of the executive member of Map The Soul embezzled the label's funds.
