The Undying Inc sound

Undying Inc mix groove metal with hardcore: slow, heavy riffs that suddenly speed up, and vocals that bark more than they growl. They like to rework their own songs, which is why "Manimal", "Evilution" and "Existence Failed" appear in more than one version. The 2010 album is the fullest statement of their sound; the later singles are shorter and more direct.
