This is many many things, but thrash is not one of them. There are about four thrash riffs on the entire album, combined with a whole slew of random influences... there's some old Swedish death, which then gets mutated down the Gothenburg path before leading into more The Haunted style bad-speed-metal riffage. This is less thrash than Carnal Forge, kids - i.e. not thrash at all. This style dominates the demo, with the overwhelming majority of the riffs of this configuration. Yay, we got ourselves another crappy Carnal Forge clone, except more leaning in a The Haunted direction.
Then when they want to throw in some groove, there is the occasional Machine Head interlude. SUFFERING!!!! (Dreamscape Domain) ... doesn't it let freedom ring with a shotgun blast? Oh yes it does. Then when they really want to go off the deep end, they break out the clean vocalist, who sounds a lot like old Candlemass, and they even throw in some clean interludes that bring in that general sound. The main interlude of Dispirited Chambers has some moments like that, and then some general riffage that sounds like Swedish crap. But that part around 2.50 is total Candlemass.
There's a few solos here too... none of them particularly memorable. Oh and then the endless crappy, choppy riffs. Probably the first song is the best, as this one is before they really ran out of ideas. There's even a thrash riff around 0.39 which remanifests itself during the final chorus. It goes well downhill from there. Dreamscape Domain starts off with a completely Gothenburg intro riff and then moves into the choppy realm of The Haunted... at the end there's some solid, though fairly generic thrash - one good riff change.
Patriots of Sin is nothing we haven't really heard before... more random silly Carnal Forge-like stuff, or maybe The Crown, except with cleaner vocals. Transcendence Duology throws in a really death-metal (old Swedish) guitar tone, especially around the 1.10 mark, which is that total Pleasure-to-Kill-thrice-removed stuff that marks generic death metal. Not thrash at all, not at this point of the evolution. Throw in one more high pitched clean vocal break (man, these just don't make any sense in the context of the songs!) and more random forgettable riffage.
Whoo, another generic band that does nothing particularly enjoyable. If you like a total mishmash of the new Swedish bullshit with some random clean vocals, then you'll like this. I see this one becoming immensely popular.
