There is no vocal fry exercises for baritone , or any drive for rock and blues singing ?

If anyone can point me in the right direction here on where to find those exercises i appreciate. 

Hi, Guilherme! I'm linking a few videos below and asking Abram for any other recs he has (for lessons on the site). Will update when I hear back!
