I'm not sure how many people have picked up on this, but there is what sounds like whispering from 3:50 to about 5:50, it goes in and out. Then again at 7:10 to about 7:31, but this one sounds less like whispers and more like a low ranting grumble. I've tried playing with Soundforge to maybe extract the voice, but I'm horrible at those audio enhancer things. I was hoping maybe someone with a little more skill in editing department could possibly help out.
As for the 3:50 - 5:50 voice, it's not Maynard saying "suck me dry" lightly, there's another voice. I can hear it when I use headphones, he's speaking right in your ear, but the other sounds drown it out so that its barely audible.
I could very well be wrong, but there have been one or two times when I picked up on the voice immediately, but it always ends up blending in with the other sounds.
It would be greatly appreciated if someone tried this for me :)
I think it's vocals in reverse. I can't make out what's being said, but I've done a lot of backwards vocal stuff in the past and that's what the enunciations sound like to me.
As for what he's saying? Try recording it backwards and playing it then. Maybe the lyrics will jump out at you.
I definitely here some, if not a lot of "SHUT UP! JUST SHUT UP! SHUT UUUUP!" in there in some spots. I think a good portion is just screaming and such as well. It gets more and more distorted by the end too.
