Well, you can't argue on tastes, DJC. I always considered Jim Morrison a fabulous rock singer, who had an amazing ability to sing rock, blues and pop songs convincingly. Anyone who listenes to live versions of "Little Red Rooster", "Back Door Man", "Light My Fire" or "Five to One" can testify to the spellbinding effect he had on his audience. It's not so much his technical ability, but more how he projects himself to the audience.
Nowhere more doubtless than on the great BMR live releases (The Doors' superb fan label, similar to FTD).
A very strong rock entertainer indeed, capable of taking the crowd on
his trip, backed with superb musicians: any other rock musician from the 60s and beyond will argue Manzarek, Krieger, Densmore were in a class of their own, better than The Stones. Agreed, Jim could be silly and self-indulgent at times, but on a good night he gave you an experience you'd never forget.
Plant is the only singer who can sound like an angry man, seductive woman, blues hound and Tasmanian Devil all in one song. That's quite an achievement. He had the charisma on stage in the 70s like Morrison had it in the 60s. Contrary to Jim, Robert didn't self-destruct. Good for him.
Elvis I would call the best and most important rock singer of the 2nd half of the 20th century. True, he popularized rock 'n roll on a global scale like no one else, but afterwards he developed himself into something more, a
pop singer. That was always what he really wanted to be, from the first day he started rehearsing and recording at the Sun Studio. Some never forgave him for that, but in doing that his worldwide appeal to mainstream audiences only grew and grew, up until this day.
There's only one other pop singer who was in his league: Frank Sinatra.
