George, I hear you guys evolving and that's good because a decent setup either evolves, succeeds or dies.
If I was producing you, I'd push you to something a shade heavier.
I can hear Jax almost hitting a "Corrosion of Conformity" type of vocal.
Try a tad more reverb on his vocal track. This last track just adds fuel to the fire and asks the question whether or not you guys are playing up to your level of ability.
I also want to mention that I hear your guitar doubling but you really aren't "moving the rock", so to speak.
On the next song, one of you should play and the other should attempt to play with it but not double the line being played. In this last one, the doubled line isn't really complimentary.
If I had to label it, I'd say it was redundant.
Good example of playing against each other in a complimentary fashion
:11 more guitar work, not doubling but complimentary.
Vocal example at 1:46-2:10ish. You could get that out of Jax's voice without too much trouble.
I'd love to hear you bust out a solo re: 2:56-3:15.
I know you guys want a certain product and that's fine.
Your material doesn't have to be anything but what you want it to be, but I honestly think you could do something similar within the genre and roll some fans at the same time.
You don't have to be as heavy but you do have to work together and you can do more with Jax's vocal.
Otherwise you are moving in an interesting direction.
I am curious to see what and where your next stop will be.
