Killers is not a concept album, but many of the songs do share a certain commonality. It is an interesting and complex thread, which explores the "killers" concept from several different perspectives including the angry searcher, the fleeing suspect, the innocently accused, the cold-blooded killer, the repentant disciple, and finally the reformed drifter. In this sense, with a bit of imagination the album can be viewed as a progression beginning with anger and violence and ending with repentance and reformation. This is not unlike 'Rime Of The Ancient Mariner', in which the mariner begins as an impulsive killer and ends as a repentant traveller and teacher.
