There seems to be an ever growing trend for bands to emphasize their "break away" from more conventional or established music, and often this starts with a titular overhaul of the classification of their music, this is often done by placing a prefix with a noun or adjective of choice (which often reflects on the genre), and then adding the suffix core. This article will touch the tip of the iceberg and introduce the reader with a number of followings who have done exactly so.
Coolidge adaption of Napalm Death's Scum, is pure genius, if you click the picture it should bring up the full sized version, perhaps it will make a fun game of spot the difference.
I think to make the claim that your band is fronted by animals and you are the first to do so, is certainly worthy of allowing you to create your own subgenre. As the term canine implies, the animal element of the band is dogs, sadly to my overactive imagination the dogs don't take on any instrumental roles, but purely a vocal performance. In a strange twist of cognitive thought processes, the only things my mind can't come to terms with the fact that the band refer to themselves as "The Orchestra", yet I find it perfectly acceptable for them to use dogs? The band make the statement that while some bands try to sound as animalistic as possible, they have never explored the idea of cutting the crap and instead actually using the real deal, namely two pit bull terriers, and they do quite an impressive job of it. I highly recommend checking them out, even on the strength of their novelty value also check out the unassociated and wrongly titled Napalm Death Chihuahua.
Grindcore and Death metal are often wrongly associated with this genre, and this has often caused much frustration to fans of Grindcore and Death metal , to explain to a general novice the distinctions. There are a number of borrowings from the death metal sphere which are integrated into metalcore, strong use of palm muting and break downs are the most recognisable traits. Songs majorly follow a set song system, featuring chorus', numerous breakdowns and few simple riffs. The general flaw with Deathcore, it tries to create a "Brutal" sound, but it is achieved in a very simple manner, and as such many music listeners find a lack of musicianship, professionalism and creativity in the music and therefore find it mundane and very generic. Additionally image seems to be of far more importance than the music, and the genre is highly commercialised and as such traditional metal heads have a general abhorrence for the genre (myself inclusive, please note I tried so hard to write that part proffessionaly and not rant on about how it boils my blood!).
Not an actual genre, but in fact a band name, these Swedish metal heads, bring in a new experimental approach to death metal, described as being as if "John Zorn would have written Brutal Truth's Extreme Conditions Demand Extreme Responses". Although a bold overstatement, it does hold true for parts, and is a fantastic listen to start to finish.
