Jay Park is an American rapper based in South Korea. He is a member of the Seattle-based b-boy crew Art of Movement (AOM), and founder and former CEO of the independent hip hop record labels AOMG and H1ghr Music, as well as the founder of the record label More Vision. Park returned to South Korea in June 2010 for the filming of Hype Nation, and in July, Park signed a contract with SidusHQ, one of the largest entertainment agencies in South Korea. Rebranding and re-debuting as both a solo singer and a rapper, Park's musical identity would lend to him partaking in the underground hip hop culture in South Korea, a rarity for both active and former K-Pop idols.
