Good question, if you go to my site I wrote an article called "Origins of Classic Rock." It's in the archives now. but it should help clarify some things for you. There's a breakdown, of artists and bands, that will give you an idea about the rock pop thing. Of course there are some artist that kind of sit in the middle of the road and are hard to define as one or the other, Elton John for instance. But classic rock is more of a reference in time or an era, rather than a genre. My mind puts the heart of the era around the Vietnam war. When music became an outlet for the younger generation to speak their minds. and facilitate significant changes in this country. Also before music became as visual as it is now. Back when I was younger, no one planted images on a screen & interpreted the music for you. You did that in your own mind. Therefore, you felt it more, and identified with it in a different way. We felt the music back then an it was very powerfull. If I had to put dates on it I would say 1960-1985
Just because a song is a classic doesn't mean it is classic rock, If it isn't in that era, it isn't classic rock. One cannot say just because a song hits the top 40 that it is a pop song either.
Classic rock includes several genres of music, as well.
You dont remember "Frampton Comes Alive" (1978) For three years that album was on the top of the charts . "Do You Feel Like I Do" Frampton used the "Talk Box" (Vocoder effect) on his guitar.
one of the lines, with the talk box engaged was, "I wanna thank you," that sounded like "I wanna (blank) you." Starts with an "F." If you catch what I mean. I guess all of this would depend on your age, If you were alive and old enough to remember, then you couldn't have missed it. That album shot Peter Frampton to an Level of fame, for a short period of time, that compares to lets say, The Beatles experienced when they came to the States.
He sold a lot of albums and made alot of Money, on that one album alone. It was recorded at the famed "Winterland Ballroom" in San Fransisco. (no longer exists)
Kay I'm, done. Wwhheeewwwww!!!!
