Metallica's "...And Justice for All" tape. I believe i was around 9.... maybe 10.
1st cds were TON's "October Rust" & Acid Bath's "Paegan Terrorism Tactics"
There's was this great radio station in upstate new york up til about '96 that played some really killer metal. I remember being in 3rd grade and staying up til like 1am just to listen. They'd play whole fuckin albums. I'd stay up to tape them.
Oh and 1st vinyl were Motorhead's "Ace of Spades" and Suicidal Tendencies "How Will I Laugh Tomorrow..." used at some hole-in-the-wall record shop in north jersey that is no longer there.
