Suddenly, albums had a theme, a style, that fed on its self, one song after another. The music had a life of its own. We couldn't wait for the next one to come out. We were mesmerized by it all.
It changed how we looked and listened to a group. With the beginning of FM, yes, I am older then dirt, the music sounded better. To be different from AM, the stations would play an album side, not just one song. It was amazing.
Elvis changed things for the moment. The Beatles changed things forever.
