lots of cool suggestions, here's mine
keys- keep them as atmosphere. guitar-style keyboard solos are evil.
bass- let mendez do a bit more, loosen up on the locked in grooves and put back in some intricate riffage.
vocals- agree that clean vocals loose their power when overused. which brings me on to my main complaint on GR..
too much clean stuff. the album's lacking in intensity, the atmosphere just isn't there like on the other ones. guess it is revery-like though. and i'm still listening to it a lot, it's damn good, just not how i expected.
i'd like the next alb to tear it up, heavier, faster, maybe some blasts and more harmony guitar. *dreams*
