i've been getting much, much better at screams. i can still hear some strain in there though and i'm trying to eliminate that. it doesn't sound quite pure enough and i think once i get that refined, i can start working more on control. i've been singing for a very long time and i think i'm relying too much on muscle memory for singing as i'm trying to scream. i have kind of taken for granted how easily a lot of vocal techniques come to me i think.
