""Terminal Spirit Disease" is an important contribution to the development of the Göteborg-style of metal which would later be known as melodic death metal.
As with "Slaughter of the Soul", there is plenty of melodic yet aggressive riffing on this one, accompanied by both mid paced drums and fast thrashy drums. This album also sounds a bit more polished and refined than "Slaughter of the Soul" and the compositions are also a bit more complex and progressive and less emotionally appealing than on "slaughter of the Soul". There are plenty of unusual riffs and unusual melody and harmony patterns - some of which are even reminiscent of the more melodic type of black metal (probably because of At The Gates' extensive use of open-stringed riffing on this album). A particularly interesting element is the use of chords that were not deployed that much in the death metal music of the time, but were more associated with alternative rock and alternative hardrock acts of the 90s. A clear example of this is the chorus of "The Swarm", which works really well.
This album would be a good entry point into the world of melodic death metal and would probably also appeal to fans of power metal and more melodic black metal, also I think some hardcore extreme metal fans would find it a tad too melodic.
