How To: Scream with increased volume for metal rock vocals

if your getting soreness and loss of voice its not due to the strain caused by overusing your vocal chords to create volume its due to the technique you use if it happens atall at any point be very careful. I tell this to everyone but you should really check out melissa cross's dvds they are a real help, through using her dvd's it helped me alot and I have a permanent dislocated vocalchord due to an assault but I can still scream as I do it right.
