Personally I had never been extremely interested in any form of music until I heard Maiden. I liked the first couple of albums from A-Ha, commodore 64 music, some few pop songs from the 80's and had a deep love for the music from Star Wars. Especially Imperial March (the Darth Vader theme). For other people it might sound weird, but I found Maiden to be a mix of all those. Only much heavier and cooler.
No Prayer For The Dying, the song, was the main song to catch my attention. It was a true "HOLY SHIT!" moment. And it's still one of my favorites. It's slow, heavy and beautiful. I don't doubt for one second that my life would have been COMPLETELY different if I hadn't heard this song.
Although "No Prayer For The Dying", the album, isn't a favorite among most fans, it has a special place in our hearts. It was our introduction to the wonderful world of heavy metal.
Cheers, TJ
