I'm not saying death metal doesn't say hooks (in fact I wasn't really even talking about them in my first post at all) I'm saying they're not as important relative to trad, and more importantly that variance in songwriting isn't as important. I agree with some of your examples, disagree with others. I love Consuming Impulse as much as anyone, and I agree that the songs are easily discernible from one another, but I don't hear it as an album where order is absolutely critical. It's a collection of bitching 3-4 minute riff-fests, one after the next. Same goes with most Death. With early At the Gates I can get more on board, although even there the second album has a pretty drastic shift into a more straight-forward headbangable blur by its second half. I can also agree with Incantation where you can have some incredibly brutal and fast material contrasted with the giant doom-influenced epics, and everything in between. The lyrical themes mentioned in Hypocrisy and Origin are more a case of the homogeneity I was talking about. "Semi-conceptual" because they share a similar basis, but afaik it's just aliens and more aliens, or whatever the theme happens to be. I don't know of a Hypocrisy album where I think "Oh yeah, that moody alien lull before the big alien peak really brings it all together", although admittedly I don't like Hypocrisy so maybe I haven't been giving them a fair shot?
