While I couldn't get my head around Flourishing's debut full length, The Sum of Fossils, I've become quite a fan of their latest release Intersubjectivity. Nestled somewhere in between their signature uncomfortable shamble and a newer, more inviting territory, Flourishing have finally bridged the gap between dissonance and warmth. The warm and robust production does wonders, especially for the hallow sounding drums and the guitars when they get all wonky. That section midway through the title track is so great and mysterious sounding and that's where they're supreme.
Hard to pinpoint, but I'd say they fall in the realm of death metal- in the most abstract kind of ways.
Immediate comparisons would be newer Deathspell Omega and Ulcerate as they've managed to create paradoxically inviting yet dissonant music in a similar way yet at a much slower pace. Saying Portal, Gorguts or even Abyssal sound similar wouldn't be a far stretch but not enough credit to the band as they're really pushing the envelope.
