Is badass.
Just listening to it again. Sounds weird like slightly nasal but deep, kind of sounds like one of The Beatles or something, that low, nasally Liverpool melodic thing.
I wish he would do more dark, weird, melodic kind of noises and rhythms like this now. Would be class if he produced his own tracks again and just focused on every aspect and layered this kind of stuff throughout it. Rather than just grabbing 50 Just Blaze beats and spitting about sluts and chickens.
He's never fully utilized his potential to make big, atmospheric music in my opinion. Something like "The Way I Am" is what I mean, but Relapse was a real step towards it, a bit of a musical step forward, as he was just sort of losing himself in a mindset and sounds.
Whatever that weird voice is, it sounds cool. He could definitely still experiment with tones, it'd sound fresh if he did a sort of low, nasally tone like that now and would be a stark contrast to all the recent yelling.
