Elvis Presley is truly The King.
 
We all can agree that Elvis is one of the greatest performers of his generation, but very few people have seen him perform right up until his final days.
 
Just weeks before he died of a heart attack in 1977, he performed Unchained Melody at a concert in Rapid City, South Dakota.
 
He seems a little rough during the introduction, but when he starts to sing, all that goes away and you’re left with a stunning song.
 
It’s eerie to hear him sing this song, especially knowing he would be gone just a few weeks later.
