Released in 1981, Killers solidified Iron Maiden's status as heavy metal pioneers. Building on the foundation laid by their self-titled debut album, the band pushed their boundaries and continued to evolve by delivering a record that combined adrenaline-fueled energy with thought-provoking lyrics and some of the greatest riffs you’re ever likely to hear. 

It’s also Paul Di’Anno's final album, as vocalist, with Maiden and is somewhat bittersweet for as incredible as Bruce Dickinson is on the microphone, Di’Anno’s gravelly singing style was perfect for Maiden’s musical style. That said, I can’t imagine Maiden’s albums post-Killers had Di’Anno remained a member of the band. 

What has remained consistent, throughout the years, is Maiden’s album artwork and Killers is one of their very best. Eddie’s demonic grin is captivating and if the music doesn’t grab you, the artwork certainly will. 

Speaking of the music, for that is the real reason we’re here, the Hi-Res Lossless Apple Music stream, an Apple Digital Master, is thoroughly enjoyable. There’s a tiny bit of muddiness to be heard, but it isn’t a detraction and once Wrathchild comes in, as the second track, all is forgotten for it is quite an audible treat. Yes, some may suggest that the Apple Digital Master is overly compressed, but for Maiden’s style of music, I find it to be perfectly suitable and the latest remasters have a little more heft in the mid to low end of the audio spectrum meaning that the thin sound of the legacy CD releases, from the 1998 remastering sessions, is no longer a cause for concern; unless you enjoyed that style of reproduction, that is. 

The Ides Of March is an incredibly ominous instrumental that sets the tone for the entire album with its haunting guitar melodies and riffs that help to form a foreboding atmosphere before leading into the high-octane anthem, Wrathchild.

Wrathchild kicks things off with Steve Harris' thundering basslines and Paul Di'Anno's gritty vocals. The song’s relentless rhythm, soaring guitar work, and catchy chorus have ensured that it’s a signature tune within Maiden’s back catalogue.

Murders In The Rue Morgue initially slows the tempo considerably with a focus on the melody, before launching into the dynamic metal-driven style that showcases Maiden’s ability to craft complex compositions while staying true to their signature sound. 

Another Life is a killer tune with so much musical depth that your mind will want to connect with every musical aspect, yet you’ll need to find an element to latch onto before the pace of Another Life gets away from you. This kind of frantic song isn’t likely to appeal to everyone, but as far as I’m concerned the shifting styles, throughout, are trademark Maiden; it’s part of what makes them so compelling.

Genghis Khan is the album’s second instrumental piece and while the vocalists of Maiden have always been commanding, I love Maiden sans the vocalist for their music is so emotive and you really get a sense of their instrumental power. From Clive Burr's drumming and Harris’ bass skill to the twin guitar attack of Dave Murray and Adrian Smith, you’ll be left speechless as many aspects of Maiden’s musical accompaniment are lost when lyrics are laid atop the musical bed. The result is that Genghis Khan is one of the greatest pieces of music Maiden ever recorded; a true masterpiece in every sense of the word. 

Innocent Exile flows nicely from Genghis Khan but it’s ultimately an album-only tune. A solid one, yes, but as a song on its own, it’s somewhat unremarkable. 

Killers is a true heavy metal classic that can be best described as an unforgettable sonic experience.

Prodigal Son is a departure from the album’s heavier tracks for this acoustic-driven tune offers a moment of introspection. The folk-inspired melodies and storytelling lyrics further demonstrate Maiden's versatility and while hardcore metal rockers may feel that Prodigal Son is nothing but filler, I’d go as far as suggesting that it’s one of Maiden’s greatest songs; a hidden gem!

Purgatory is a fast-paced relentless onslaught of music; a polar opposite to Prodigal Son. If nothing else, Purgatory is indicative of Maiden’s early raw sound signature. 

Drifter closes the album with a final burst of palpable energy that will compel you to play the album again, for Killers can rarely be heard a single time. 

Killers marked a significant step forward for Iron Maiden, both in terms of musical complexity and thematic depth; even though I consider their self-titled debut to be a masterpiece. Regardless, when you combine the band, Steve Harris’ driving basslines, and Paul Di'Anno's raw vocals, you get a sound that has not only influenced generations of metal bands but stands as an influential chapter in Iron Maiden’s legacy.
