I freely admit my knowledge of Jungle Rot's musical back-catalogue is rather limited, but I'm aware that the quartet has been praised for their simplistic back to basics death metal and I can easily understand why. The music is old school death metal in the vein of Obituary without saying they sound too much alike. Style-wise the unit proclaim to have more in common with Slayer and Sodom than with most other considered death metal nowadays. Listening to War Zone that statement makes sense, but the groove and catchy songwriting remind a lot of Obituary and to a degree also of Skinless.
It's clear that Jungle Rot is not about the speed or brutality. The band focus more on the heavy and groove aspects of the music which is also what make it a little different. Sure there's hardly anything unheard in this, but still it set the Americans somewhat apart from the vast majority of other death metal bands. This is also what makes War Zone an interesting encounter. You won't really find any fancy solos or other gimmicks on War Zone. The technical finesses in the music are boiled down to a minimum, only relying on the groove elements, but it works without complaint. The production is fat and full, just as it should be with this kind of music.
If you don't demand too much of your music and like it simple and stripped down then War Zone is definitely a recommendable purchase. Jungle Rot's music doesn't take long to analysis, but regardless of that they definitely got something great going on.
