well after listening to butcher the weak, planisphaereum, and supreme vehemence, I have to say vvvvv's warning was apt: Wormed emerge as my favorite of the bunch. cool theme, crazy vocals, and just all around good music. vomit remnants are likable but, much like dying fetus often does, it frequently sounds somewhat samey to my ear. devourment are good but, again, I think I'll need to listen more to get really into it.
the part of this style I'm enjoying the most is its main distinguishing feature- the brutal breakdowns/"slam" sections. Wormed's Geodesic Dome has a particularly cool section starting around 1:50 that absolutely destroys (slow tempo followed by this looooong froggy groan). although I dig the frog groans, in general guttural vocals don't matter a hell of a lot to me one way or the other; intelligible lyrics is one way bands like Skinless keep my attention, but some of this stuff is catchy enough that it hardly matters.
for further recs, lots of slamming, and as much technicality as can be expected to exist in such a subgenre (drumming, primarily). anything that varies/distinguishes songs is helpful given the nature of the beast (that doesn't need to be excessive sound sample usage, though!)
thanks for turning me on to this stuff, and the blog is cool, too
