The Immortals are a band consisting of Belgian electronic musicians Maurice Engelen and Olivier Adams, best known for their work in the controversial techno/industrial dance band Lords of Acid.
The sideproject was created for the first Mortal Kombat soundtrack in 1994. However they debuted their track "Techno Syndrome (Mortal Kombat)" in 1993, when it was released as a single; it was also used in TV advertisements for the Mortal Kombat Movie commercial and Mortal Kombat: Live Tour. The song was released the same year when the game was released for home consoles. The track has also subsequently become known as "the Mortal Kombat theme song". They also appeared for a set of remixes of the JX track "Close To Your Heart".
