No idea.
Thinking back my own record collection started around 1988-89 and I got a picture somewhere where I can see 4 albums being:
Metallica Ride the lightning. Still got it
Metallica Kill'em'all. Still got it
Iron Maiden Somewhere in time. Gone
Iron Maiden Seventh son of a seventh son. Gone
I also recall a record with different rap artist on it. Still got it. It's called Free Rap.
I do recall order the Jive Bunny and the mastermixers record around the time it came out. Got a better copy these days.
My sister gave me:
Mucky pop Boy in a mans world. Still got it
Mucky pop Now. Still got it.
First one must be based on my taste for music and I got into a bit of rap style back in 1987 when the first real Danish atempt came out.
I did not hear any heavy stuff untill the fall of 1989 so the Jive Bunny or Free rap could be one of them. I still dig that Jive Bunny record. Also my very first stereo with a recordplayer built in (crap) came around 1989. My collection of records took of from there.
