The Beatles,

all big Elvis fans, displaced Presley as the biggest rock act in the world in 1964. What's more, they did so by writing their own material and playing their own instruments; something Elvis had never been capable of, or particularly aspired to. They, and the British and American groups the Beatles influenced, were not shy about expressing their opinions, experimenting musically, and taking the reins of their artistic direction into their own hands. The net effect was to make Elvis Presley, still churning out movies in Hollywood as psychedelia and soul music became the rage, seem irrelevant, even as he managed to squeeze out an obscure cover ("Tomorrow Is a Long Time") on a 1966 soundtrack album.
