Ok, i'll also pick on "she was just another system slave", a cod-political line that hides so many things that aren't being properly explored just lazily tossed in, and "the world is just a spinning ball of confusion that no-one understands", which is pompous and hilarious given the depth of knowledge we have about earth. oh and "she was booorn... in 1617....". just doesn't work with that kind of aggressive music and delivery, sounds like a line from a history book delivered as war cry.
but i challenge ANYONE to do such a good job of constructing memorable melodies and phrasing over the kind of riffs that loomis writes, he does a great job of bringing something to the table. it's a little like labrie, another polarising singer, does a great job of keeping up with his band, given how involved the music he's singing over is.
screaming/growling, for example, is an easy option, it takes guts to SING in a metal band these days, and though nevermore expertly use different modulations in their songs, encouraging melody over the top, finding something that really works and makes the metal workouts into SONGS, indeed, fronting a band of that level of technical sophistication, must be an occasionally thankless task.
