have any of you guys ever heard when this is done, sounds strange imo, i know that this guy does it

any of you know any people that have ever done that, by their own means or been forced into it? maybe even professional bands!!??
oh god that was horrible
anyways alice in chains had alot of vocal effects used.
Send me off to bed forevermore.
i dont know, but i think it will sound all muddled up and not clear....+ if the whole song is gonna be like that than it will be boring...not cool :/
