TraxX originally debuted under the name TRAX in 2004, and was a four-piece EDM rock band under SM Entertainment and X Japan’s Yoshiki.

The members at the time of debut was Typhoon Jay (leader and vocals), Rose Minwoo (drums), Attack Jungwoo (bass), and Xmas Jungmo (guitar) and the band name was an acronym meaning “Typhoon Rose Attack Xmas” and also used the first letters of the members' stage names.

In 2006 and 2007, members Rose Minwoo and Jungwoo departed from the group, leaving the band a duo. As a result, the band later renamed themselves THE TRAX, and later, simply TRAX.

TRAX would once again change their name to TraxX on March 26, 2018, when DJ and producer Ginjo joined. The band eventually disbanded in April of 2019, after two members left SM Entertainment when their contracts expired.
