i was practicing growling one day and in one of my growls i felt a gargle in the back of my throat. i was unable 2 repeat that since then and was wondering if any1 knows how to do that again

try using the area closer to your tonsoles (i have no idea how to spell that) to get that, above your false chords

Haha you just mixed an exhale guttural with a growl. The effect is a very low, nasally and wet sounding growl. ^The guy above me is completely correct :]. If you can single out the upper area then you can do just exhale gutturals which are what bands like abominable putridity and cephalotripsy use.

Once you get it, it isn't difficult so you might find yourself wanting to mix the growl with the exhale guttural instead of just using the exhale guttural-for the challenge. Exhale gutturals are waaaay too easy.

Try sounding like the cookie monster. It is the same thing. After you do that, growl at the same time as you do exhale guttural and boom-a new screaming technique is born.
