I was about 8 years old when Elvis came out. Before that, you had Bill Haley sing rock around the clock. Even young, I could hear a new sound emerging..
As stated, I enjoyed the early rock prepubescent. After Elvis was drafted, and the other southern rockers got in trouble, the music scene drifted up north under control of New York. There was some good doowop, but most of the music was ballad oriented.
Then in 1964 when I was 15, the Beatles hit the scene. I think kids were starving for guitar based bands again. A new age was born and I rode it for ten years.
After ten years the sex, drugs, and rock and roll era started winding down. I listened to the new songs for about five or six more years and then no longer listened to new music unless my kids were listening. Some of it was darn good in the 90s. Went with oldie stations that have now disappeared so I use you tube.
When I say it wasn't completely generational, it's because people younger and older than me, enjoyed a lot of music at the same time, but the younger crowd was tuned to 1970 music and the older crowd was tuned to late 50s music. Early 60s didn't do much for me music wise.
