i weighed in on the car assuming its not ezxtensively updated/modded, i vote 70-71 is a polara as monacos had a single tail light refrector combo look. polara had a split tailight treatment like the video.
as to music, not my personal style. still i dont begrudge any fan of any age -we like what we like.
however, now that i am old, i do note some individual song/styles i can't listen to. it's like they/it get on my nerves. i dont' t know that its age, and nothing wrong with my hearing, its just i have difficulty liking certain song/genres i even owned/liked 40 years ago.
mosh pits pre-date my youth as i dont recall encountering them until mid 80's when i was out of college. abuut '87, i went to an "outdoor concert" in the northwest US (Portland area) on a road with younger colleagues (i was approaching 30). Rather than keep my a** in the bleachers, i took the field in the front of the stage. it was a rock band but not a metal genre, and next thing i know people were crashing into each other. apparently having fun. i played football (bad trainining) and held my own briefly. Kind of against the rules I learned later, but at the time I was afraid I was gonna get killed
