Review by Morpheus Kitami for Dark Angel - Darkness Descends (1986)

While Slayer decided that the speed and aggressive of Reign in Blood, other bands decided that this was too soft for them. Dark Angel is one of the bands most known for doing this.
I kind of disagree with this common view of the album. I'm sure on a BPM and note for note level, Darkness Descends is far more aggressive. But Reign in Blood has more factors contributing to it than pure aggression. Darkness Descends has a lot more warmer and less slick elements to it, having more amateurish production. In line more with NWOBHM albums and subsequent early thrash albums not feeling the need to come into a room and scream that they're thrash metal albums. And compared to some later albums in general, this can come off as downright quaint at times.
Which isn't a bad thing, one's creative nature dies when one tries to limit oneself to what "should" be in a genre. Something that bands after Dark Angel would surely fall into, because arguably these guys don't expand on the formula all that much. Which is fine, ceaseless brutality is often boring and renders itself lifeless. In this regard, Darkness Descends comes as a missing link between early thrash and what British thrash would end up sounding like, a balance of the extremes.
But this album does feel a bit style over substance, even for the early years of thrash. Riffs are often of little importance to aggression, which considering the aforementioned, leaves it feeling unmemorable. Despite listening to it a number of times I can barely recall anything beyond a fuzzy feeling once the album is over.
It's a pretty good album, but ultimately you can see the faults that would eventually result in the genre's death for a while.
