I am starting a ten part list of my favorite bands I have heard that formed this last decade. I will then have an honorable mentions post. This is the first part, and these are not ranked.
I have covered this band before, when I did the piece on Australian "war metal". Trench Hell is a thrash metal band with occasional black and death metal influences, although thrash is their root sound. In particular, Trench Hell seems most interested in playing a style of metal heavily influenced by Celtic Frost's sound on To Mega Therion. Their sound is gritty and raw and they closely approximate the sinister guitar tone Frost made famous on their riffs. Their singer has even come close to perfecting Tom G. Warrior's trademarked grunt vocalizations.
This is not to say that the band is a Celtic Frost copycat, merely that the influence is fairly clear in their music. Nevertheless, Trench Hell is an extremely effective and aggressive thrash metal band. They play fast, furious, and ugly, and steamroll the listener with their sound.
I own two releases by Trench Hell.
The first release is the self-released demo Alcoholic Disaster, which featured two original songs and a cover of a Hellhammer song, thus further reinforcing the idea of the band's influences. The songs are raw and fast, and an excellent hint at what was to come from the band.
The second release is the Southern Cross Ripper EP. This album represents the band's current sound. It features six songs that are much more polished, while losing none of the band's aggression and power. The band continues to grow. Hopefully we will see a full length at some point in the near future.
