Frankly speaking, all of today's singers(bad term) are just shouting and screaming and most likely that is because they are trying to be heard over those screaming guitars and hammering drums.

Gary - I remember Glenn, Harry, Dorsey brothers when they were still together, Less Brown, Stan K and on and on from that era - I can remember two singers who demonstrated they could have sung with that group because they have recorded singing in that genre - Linda Ronstadt and Christina Aguilera - Yeah I couldn't believe it either. ;-)
