One of the most popular American singers of the twentieth century was Elvis Presley. He made the rock ”n” roll music popular all over the world, He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.

Elvis Presley was born in a poor family in 1935, His parents were simple country people who often took him to church, where he learned to sing, and he never forgot the kind of songs that he used to sing in church as a child.

When he was young, Elvis moved from Toledo to Memphis in Tennessee, where he attended high school, but he was not a good student, His only real interest was singing. He began to sing in the style that is called “country and western”.

In 1955 he recorded some songs for his mother’s birthday. The people at the recording studio liked his singing and his music. It was country and western music, but it also sounded a little like the music which black people used to sing in the American South. It was called “blues”.

Shortly after that, Elvis met Tom Parker, who became his manager and arranged (安排) concerts for him across the United States and new recordings as well. Soon Elvis became famous around the country. Later Elvis went to Hollywood and began to appear in films such as Love Me Tender and King Creole.

But Elvis found it difficult to live with success. Like many other famous people, He began to take drugs and his health started to suffer. When he died at an early age of 42 in 1977,his many millions of fans were shocked, “The King Is Dead!” the newspaper said, But today his memory and his music live on and will always be remembered as the King of Rock “n” roll.
