Haha... Yeah, fair play. Nothing against trying something new, I was just agreeing that particular example seems to be out of his comfort zone to the point that it can't be replicated live unless those filters are used on his voice again. I do think comparing it to an external instrument is different in this case though, but if we're going to say it's basically the same thing then I'll make a double standard for it.
If I could articulate more (now you're gonna make me overanalyse an off the cuff thought
), I guess it'd be more like saying, JP shouldn't try make his guitar sound like a piano, it wouldn't sit right as a listener. (Not that I can talk, I love making keyboard sound like a guitar so if you have a means to make a certain sound, go for it I guess). But it feels like it's using effects to go beyond the boundaries of the player (or singer in this case), into a range or style that they can't normally pull off (performance quality would be subjective of course). Chorus effects, subtle pitch correction, minor enhancements and whatnot I have no problem with so I guess what I'm almost trying to say is singers that can't scream shouldn't try unless they can do it 'good' (or not come across contrived) because it's just not what they do well - which I concede is a bit unfair and if it were a rule would probably have many exceptions. Maybe JLB is one of these exceptions because I find the screams impressive in TWS, BMUBMD and even the live Octavarium screams, although less impressed with some attempts in other songs eg ACOS and TGP have moments that I'll call 'half arsed almost screams' that slightly miss the mark.
But I see it as a similar complaint as: This piano sounds like a casio, these string samples sound flat and lifeless, these drums tones sound dry. - All legitimate sounds and styles on their own but it still sounds unnatural for whatever reason to the listener, possibly related to the preconceptions of what they expect to hear when a certain instrument is playing.
