Okay, so, Serpents Kiss...
The whole main riff concept is awesome, reminds me of the Sins and Shadows style of taking a main riff idea and doing permutations off of it. Highly digging MJR's tone - in fact listening to it back to back with Inferno, his tone is massively improved. Even tho it's him and I should expect it by now, the solos are SO clean.
Russ could have put a little more melody into the vox... you can kinda hear how it should be and its one thing to gruff up an implied melody, but this borders on ditching the melody too much. Like Inferno is pretty gruff but you can still get the melody out of it. This is a bit more of a stretch to find the melody.
Unfortunately that one little ascending run in the lick was already ruined for my by Kirk Hammet (you can tell its open string, hammer on, hammer on, repeat). I just wind up feeling like its cheap and amaturish to do that, mostly just because of how it's played.
Overall, though, very impressed, my interest for this album is definitely peaked.
