A good example of what I'm talking about is when Van Morrison sings with that "raspy" voice in, say, Real Real Gone (especially the new recording on "Duets").
When I try to mimic the raspiness, it sounds good (in my opinion), but it leaves my voice feeling a little raw (though my voice is still crisp). I wish I could show an example of what I mean...
Anyway, this rawness I was talking about, is it causing any actual damage? Or could it be strengthening my voice in a "no pain, no gain" type of way?
EDIT: I uploaded my soundclip! http://vocaroo.com/i/s0z0O14J2XtT
That's what I mean.
