Opinions please?

This is a forum for helping each other out, so I have a performance question.

I seem to have some kind of growl that developed over the years, especially in bluesy songs or when I get to the hard driving notes. I have seen a couple of mentions about that, so here goes my vulnerable question. Should I try to eliminate or lessen that growling thing? Because I know it will come out in this song, it is like a monster in me.

lol, thanks for your thoughts.
