[Praisecore]

well i can scream pretty good its like august burns red, winter solstice, As I lay dying stuff like that yea. the thing is sometimes there will be like a higher pitched sound also coming out of my mouth with it too like i mostly hear my lower pitched growl scream what ever you guys call it it's just like in the background. i don't like it. what is it? and how do i get it to go away?

Sounds like a few things, either your hearing the scream resonate in your mouth which shouldnt be audible to anyone else, or if you also hear this on recordings it sounds like it might be air, so get a windscreenpop filter.
