 Xysma's first demo, "Swarming of the Maggots", was shared widely via tapetrading and became a cult classic (it was remastered and released on the 2004 Xysma compilation CD).Musically, the band were inspired by the early classics in the genre like Carcass and Napalm Death.With the following mini-albums, "Above the Mind of Morbidity" and "Fata Morgana", the last one released in the United States through the infamous Seraphic Decay label, Xysma evolved towards less extreme metal.
