Musically, there are some issues with the sound. Evidenced by the first track "Embrace the End" is a strange combination of modern metal influences and throwback thrash. One thing that does come across positively is the feel of energy the band has. Live, they put on a decent show for a local act, and the passion that was present in the flesh is also present here. The vocals are a major reason for that. There are a few different styles present here, both some growls and some thrashier yells as well as some cleaner, raspy moments. Second track, "Crucify" has some of the best parts on the demo and the worst parts. It also is the weakest sounding vocally. The vocals are too low in the mix along with the drums. The chorus is pretty bad with an amateurish breakdown and off-key clean vocals that follow a poor transition. Though the guitar riffs are more interesting and memorable at times, a really bad guitar solo performance brings down the track. An intermediary section with some sort of narrated growling demonic voice also appears out of nowhere. "Breathe" provides evidence that the bass has no tone, sounding like burps inside a balloon full of mud. The fact that all the guitars follow each other, offering no variety also makes everything sound a bit boring.
The final track on this four song demo is "Manic." This is the highlight for me because it sounds like it could have been written in 1993 or 1994 by some obscure doom death project like Gutwrench or Solstice. It reminds me the least of modern metal and mall-core. The vocals are pretty bad at times, particularly the spoken/raspy ones in the beginning but the higher register clean vocals sound a lot like Mystifier's The World Is So Good That Who Made It Doesn't Live Here, an album which most likely is not an influence on any of these guys since the vast majority of humans are not cool enough to have heard Mystifier, much less one of their less talked about releases. It's a weird track and the most worthwhile on the demo. Glad to have heard that one. More tracks like this, some extra effort put into the image of the band and general experience and increased musicianship could separate Absense of Salvation from being a local band to something more.
