I have more say in the first two.
Elvis Presley seems to be before the Beatles. His music is actually a very special kind of music, which can't be completely called rock and roll. It combined many American music styles at that time and created a new world.
The Beatles are different. The music environment in Britain is actually relatively simple and orthodox. You listen to their music.
Most of them are simple and warm British styles.
If Elvis Presley's music is a free and comprehensive spirit, then the Beatles represent the persistence of traditional values. The Beatles' influence in the world seems to be greater than that of Elvis Presley. Their lyrics have won the greatest famous sayings in Britain, surpassing Churchill, but their influence on the United States may be different.
As for Pinkployd, he seems to know that western thoughts have become more and more diversified since the 1970s. On the basis of encouraging personal value, the development of personal spirit has appeared in various extreme situations, especially in rock and roll, which is the natural result of encouraging individuality and rebellious spirit in the West.
