I was 15 in 1988. Had I listened to something 30 years old then, I'd be listening to something from 1958.
1958 folks. In 1988.
I was listening to GnR and AC/DC. If I had have been listening to "new" stuff that was 30 years old ... At The Hop by Danny & The Juniors.
The Beastie Boys are not "new".
You need to roll the dice to be in the game.
