+1 on "The Grudge".
How about Glenn Hughes? Still bringin' it at 70+ Check out some of his later work with the Dead Daises.
"Like No Other (Bassline)" off Holy Ground is one of my favorites. He rips off a few good screams as well.
Favorite scream in rock?
Robert Palmer lets rip a tremendous, rolling scream near the end of "Sneakin' Sally." "The fact is ... rrrooOOAAAHHHHH .... JUST BEEN CAUGHT."
What's your favorite scream, shout, or yell? Other than Roger Daltrey's, of course.
