I, Human is the second full-length album by Singaporean death metal band, Deus Ex Machina, and the first to feature a permanent vocalist, giving it more uniformity in contrast to The War Inside, which had a different singer for each track. Musically, it is an edgy mixture of Death Metal and Thrash Metal with Melodic death metal and Progressive Metal interjections, coupled with a diversified vocal approach. The lyrical content of the album deals with the future: Cloning. Specifically, questions regarding its use, legality, implications and the possibility of a world full of clones fighting to gain their own identity. The concept is based on Isaac Asimov's novel I,Robot, but also draws influences from other science fiction works such as Blade Runner, The 6th Day, A.I. Artificial Intelligence, and Warhammer 40,000. Each songs discusses the ethical issues pertaining to cloning, shifting from first person to second person to third person perspective. The band further divulges the mind frame of an unnamed clone character as it gradually realizes it is a clone, upon awaking from what it thought was a dream. In its desire to strive for acceptance as an equal, the band delves into its thoughts, fears and plans and invokes these emotions and transforms them into an aural assault with thought-provoking lyrics.
