“There were no great classical rock vocals before 1960?
How old is this author?”
Classic Rock is loosely defined as music from the mid-late 70’s to early 90’s. Given that anything before 1975 isn’t considered. Not that it wasn’t good music it just doesn’t fit the category.
With that said the author included a Beach Boys song and a Beatles song on his list. I guess they were his guilty pleasures.
