Mutation were a short-lived Singaporean death metal band who only released 2 demos in 1991 and recorded material for an EP in 1993, but that EP was not released until 2006 by the mighty Nuclear War Now. This is rotten, sickening death metal.
There is only 1 link because I put the demo and the EP in the same folder. As usual, these are ripped from my own copies. Enjoy
