Today we still listen to, discuss and debate albums and artists from let's say 1950 to the present day, a span of some sixty years give or take.. I will not mention the artists as we all know who they are basically. This is generally identified as Classic Rock.
They are still here one way or another. Why ?
The obvious may be because the music set the foundation for future rockers to be inspired by so they could create their own original music.
Perhaps the music "back then" was incredibly just plain "good''..I'll use this expletive ...others could be excellent, great, the dreaded Best word, so on. !
The term Classic Rock may be in the name itself...Classic...it will be here for a long time as Classical Music is still here today !
