I'm not sure what determines "King of Rock and Roll"?

However rock and roll started with Chuck Berry and "Maybellene"; he took music and the guitar to a new level. In my mind that overshadows the accomplishments of the others.

i am the king of rock n roll

completely

I think howlin wolf gets way overlooked in this conversation. Yes, he was blues, but thats where Rock came from. His style of blues was different than any other blues artist. He had such a powerful voice and stage presence. He rocked the house harder than any other blues musician. And don't forget, they call him the "rocker".

Elvis is my winner!

Chuck I guess.

it has to be chuck berry!.. whenever 'You never can tell' comes on .. you know what time it is!! time to rock and roll! xx

It's Elvis no matter how many other artist you list, because without Elvis rock-n-roll does not exist. Without Elvis there is no Rolling Stones, Beatles, Zeppelin, etc. People argue that those bands and all artist after would have probably still come after him and maybe that's true but think about all of those artist Elvis inspired to do what they did, Jimmy Page has stated that hearing Baby Let's Play House inspired him to start playing guitar. And on another note he wins because he was the first. When he went to Sun Studios in 1954 and recorded "That's Alright Mama" that's when it all started. Somebody else would have come along mostly likely started the whole thing but since he was first, he is the king. I could keep going but this sounds pretty good.

Elvis died on his "throne"

I respect the effort you put into Making a case for Elvis, but as the person above you stated, he wasn't first, like you said. Maybe he is the king, but he wasn't the father. Nicely said by rockabillynblues

The title is for Elvis Presley. He made a great milestones while being around for only a short time. Elvis Presley in my view is someone who was able to find something great that people apperciated. I mean so many people know Elvis and want to know more about him than Chuck Berry although he was a better guitarist than Elvis ever was.

But overall, star and talent, I'd say that Elvis was better than the other two.
