TraxX (Korean: 트랙스; RR: Teuraekseu, formerly known as The TRAX and TRAX), was a South Korean EDM trio that consisted of Jay, Jungmo and Ginjo. Originally a four-member rock band formed by SM Entertainment and X Japan's co-founder Yoshiki in 2004, it consisted of Typhoon Jay (leader and vocals), Rose Minwoo (drums), Attack Jungwoo (bass), and Xmas Jungmo (guitar). Their name is an acronym of "Typhoon Rose Attack Xmas", the members' nicknames.
No Min-woo and Jungwoo left the group in the period between 2006 and 2007. This resulted in the band becoming a duo with the remaining members being Jay and Jungmo. They changed their band name from The TRAX to simply TRAX. The duo kicked off with the release of the EPs Cold-Hearted Man (2010), Oh! My Goddess (2010), and Blind (2011). Thereafter, the members went into individual activities, with Jay pursuing acting and Jungmo collaborating with several artists.
On March 26, 2018, TRAX changed their name to TraxX with DJ and producer Ginjo joining the group and changing their music genre from rock to electronic dance music. TraxX unofficially disbanded after 2 members left SM in April 2019.
