Hi everyone,

I'm looking to start up a punk band to have as a side project for my acoustic stuff but I'm stuck on the vocals. I want to have a kinda harsh scream sound.

Any help would be really appreciated, thanks ๐Ÿค˜๐Ÿป
fhjmusic Hi and welcome to forum, check this video about High Screams and other videos on this channel to understand the key points on these vocal techniques

What concerns all screaming vocal techniques, that they don't go well for the first time, you need some time and practicing for achieving good sound. 
And be accurate and patient with these techniques, it's a short way to break your voice, so if you feel any kind of pain (for the first time you'll feel it almost immediately), you should stop practicing and wait till your cords are restored.
