First Metal Album

First metal album I heard would have been Saxon "Power & The Glory" and I was about 13 so we are going back 26 years (clucking bell!) and the record was around 6 years old at that point.  My cousin lent me his entire vinyl collection I remember which had all the Maiden records inclusive of "Somewhere In Time", Rush "Moving Pictures", UFO "Strangers In The Night" and some punk records that I quickly dismissed,

First album I bought would have been Obituary "Slowly We Rot", I remember picking up the album and looking at that artwork and thinking I had to have it.  I took it back to my grandparents house as my dad worked nights and was in bed, my granddad was a hi-fi buff and had some neat equipment and he let me put the record on in his den.  He stayed for a minute after it started because he was convinced the LP or his equipment was faulty because he had never heard anything like it.  I told him it was supposed to sound like that and he just left the room looking very puzzled.
