Recently discovered online by netizens, a different vocal track of TVXQ's song titled "Maximum" was brought to light through the members' practice video. This track off of their "Keep Your Head Down" album, which was released early this year, seemed to be originally sang by all 5 members -- including the vocals of JYJ.
Speculations of this song may be that it was recorded a while back, before the hiatus in late 2008 and early 2009. In TVXQ's latest Korean album, the song was re-edited featuring only the vocals of Changmin and Yunho.
Check out the practice video below. What do you think of both of their tracks?
