When I first heard Elvis’ voice I just knew that I wasn’t going to work for anybody; and nobody was going to be my boss. He is the deity supreme of rock & roll religion as it exists in today’s form. Hearing him for the first time was like busting out of jail.
~Bob Dylan (1987)

His music and his personality, fusing the styles of white country and black rhythm and blues, permanently changed the face of American popular culture. His following was immense, and he was a symbol to people the world over of the vitality, rebelliousness, and good humor of his country.
~President Jimmy Carter
August 17, 1977

Elvis Presley is a supreme figure in American life, one whose presence, no matter how banal or predictable, brooks no real comparisons. … The cultural range of his music has expanded to the point where it includes not only the hits of the day, but also patriotic recitals, pure country gospel, and really dirty blues. … Elvis has emerged as a great artist, a great rocker, a great purveyor of schlock, a great heart throb, a great bore, a great symbol of potency, a great ham, a great nice person, and, yes, a great American.
~Greil Marcus (The Village Voice – Apr 7, 1975)

My Way:

And now, the end is near
And so I face the final curtain
My friend, I’ll say it clear
I’ll state my case, of which I’m certain

I’ve lived a life that’s full
I’ve traveled each and ev’ry highway
And more, much more than this
I did it my way

Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was one of the most popular American singers of the 20th century. A cultural icon, he is commonly known by the single name Elvis. He is often referred to as the “King of Rock and Roll” or simply “the King“.

 I know he invented rock and roll, in a manner of speaking, but … that’s not why he’s worshiped as a god today. He’s worshiped as a god today because in addition to inventing rock and roll he was the greatest ballad singer this side of Frank Sinatra—because the spiritual translucence and reined-in gut sexuality of his slow weeper and torchy pop blues still activate the hormones and slavish devotion of millions of female human beings worldwide.
~Robert Christgau (December 24, 1985)

Elvis Presley may be the single most important figure in American 20th century popular music. Not necessarily the best, and certainly not the most consistent. But no one could argue with the fact that he was the musician most responsible for popularizing rock & roll on an international level. Viewed in cold sales figures, his impact was phenomenal….
More important from a music lover’s perspective, however, are his remarkable artistic achievements.

From Elvis In Memphis (1969):

….The result was one of the greatest white soul albums (and one of the greatest soul albums) ever cut, with brief but considerable forays into country, pop, and blues as well. Presley sounds rejuvenated artistically throughout the dozen cuts off the original album, and he’s supported by the best playing and backup singing of his entire recording history.
