So after listening to it for the last two days, I agree about the mix. It's not that it's bad per say, just odd. Actually, I find it truly brutal (and not necessarily in the broootal metalhead sense). It's kind of like a constant bludgeoning with a large, dull object. I think it's a blend of the kick drum and the guitar frequencies like you mention. It definitely does not have the snap of Obzen or the precision and finesse of some of their other albums. Overall I like it (hey, any Meshuggah is better than no Meshuggah) and a few of the tracks have some great grooves. It's just an oddity that I have a headache after listening to a song, even at a lower volume...I don't recall this ever happening before with any band (and I tend to listen to some pretty crazy metal). It's like it was mixed to aurally beat you into submission.
