(the following I have said more or less in the past, so some of you may have read it already)
My take:
Killers has one of the most "in-your-face-productions" of all Maiden albums.
Most tracks are not so melodic as most other Maiden albums. Still I like side B very much (apart from "Drifter", which is very low on my ranking). My favourite Killers-moments are "Purgatory" (great combo of speed and melody), the instrumental mid-piece in "Prodigal Son" (the only song never played live) with its spineshivering solos, "Wrathchild", the cool harmonies of "Murders In The Rue Morgue", the aggressive mid-part in "Another Life".
Surprisingly, my favourite track is "Genghis Khan". The way this song changes into the groovy end, with the great melody played by Dave on the left side and the melodic harmonies makes it one of the coolest Maiden parts ever! Though this commentary seems very positive, I still like it less than the debut which made a better overall impression. Conclusive thoughts:
-Aggression
-In Your Face
-Best production for Clive's drums
