A very dark and heavy sound starts off the demo along with some low end deep death metal growls that also bring in few pitched screams and the music starts to speed up and incorporate more blast beats and the riffs also use tremolo picking at times and the songs also bring in a great mixture of slow, mid paced and fast parts.
Most of the tracks are very long and epic in length and also add in a decent amount of morbid sounding melodies at times and when solos and leads are utilized they are very dark and chaotic early 90's sounding death metal guitar solos and leads and the slower sections also bring in a very heavy dose of doom metal.
Negative Vortex plays a style of doom/death metal that is very dark and heavily rooted in the early 90's while the death metal side of their musical style mostly dominates the songs and they also play a bit more faster than most bands in this genre, the production sounds very dark and heavy while the lyrics cover darkness and death themes.
In my opinion Negative Vortex are a very great sounding doom/death metal band and if you are a fan of this musical genre, you should check out this cassette. RECOMMENDED TRACKS INCLUDE "Chant For the Undertaker" and "The Burning Orb". 8 out of 10.
