I think Sugar Hill Gang’s self titled album.A but if a cheat as it came out just into 1980, but the single rapper’s delight came out in ‘79 so I’m firmly claiming it for the 70sOf the back of its success came an entire music genre
Have you ever heard the Fatback Band’s rap? This came out before Rappers Delight in early 79, if I recall correctly. I did buy the album before Rappers was released, that I do remember.https://www.youtube.com/v/bJluajMeeys
