How do you scream like Adam Gontier?

Answer 1

If you are a screamer, you will likely have difficulty not knowing how to ease up a little and want to "Killswitch Engage" scream everywhere, which is different than what Adam does.

Also, I suggest too that screamers work on tone and sustained pitch during the singing part which sometimes is a problem for screamers, although they are blessed with the ability to get a nice resonating scream.
