I'm a vocalist trying to learn new things.

1. My inhaleds are wonderful. But they're frowned upon so I need more help with my exhales.

2. I need a good explanation of high screams and black metal highs. Like a step by step process if possible.

3. My vocals right now are very throaty sounding, like Tommy Rogers from between the buried and me. I need to get them sounding like Brooke Reeves from Impending Doom.

I'M OPEN TO ALL SUGGESTIONS. PLEASE HELP ME OUT!!!!
