"Enter The Realm" was the last demo Iced Earth recorded in the late eighties and it was the turning point in Iced Earths history. They pressed around 1000 copies of it. Germany's RockHard metal magazine voted it "Demo Of The Month", at the end of 1989 it even became "Demo Of The Year".
All of the songs recorded can be heard on later albums, the original versions of 4 of the 6 songs in a remix on "Days Of Purgatory", the other ones on "Iced Earth".
