Iron Maiden always sounds a little bit too much to me; too much arpeggios, too much theatrical singing/screaming, too much galloping drums, and not enough room to breathe. But it's the accumulation of these that makes it too much, individually this album is full of great songs and it's without a doubt a classic in the genre.
This album was my introduction to heavy metal, and what a great introduction it was too! Nerdy references to cult sci-fi like Children of the Damned and the Prisoner, songs about marauding Vikings and Wild West battles, occult spookiness and a suspiciously detailed knowledge of the price list of infamous brothel madam Cynthia Payne. The music is top notch all the way through, with galloping drums, virtuoso guitar, solid bass , and Dickinson’s soaring vocals.
