Iron Maiden's sophomore effort, Killers, is mostly composed of pre-existing material that had been left off the debut, with just a few new additions. It's certainly a better-sounding release than the debut, with new producer Martin Birch beefing up the band's studio presence and lending their instrumental attack a newfound clarity that throws their considerable skills into sharp relief. In fact, this helps mask the fact that the songwriting isn't quite as strong overall as it was on the debut. But the teaming of new guitarist Adrian Smith with Dave Murray forms the most formidable twin-guitar attack in heavy metal, outside of Glenn Tipton and K.K. Downing. Plus, bassist Steve Harris' busy, driving lines are now consistently audible in the mix. The resulting instrumental fireworks are what truly make the album tick. That said, there's a much smaller percentage of catalog standards here than on the previous album. "Wrathchild" is the standout, re-recorded here with Smith on guitar from an earlier version for the Metal for Muthas compilation. There's a fair bit of unity in the lyrical themes, with a parade of murderers, fugitives, and characters otherwise torn from their roots. "Murders in the Rue Morgue" is a first-person retelling of the Poe short story, and the title track is another highlight, with Paul Di'Anno turning in an especially menacing performance. The single "Purgatory" has a catchy singalong chorus and a tempo worthy of Mot”rhead, while "Twilight Zone" (not included on the U.K. issue, but added to subsequent releases) scraped the bottom of the British charts. The biggest departure here is the almost Supertramp-like prog-pop of "Prodigal Son," a melodic, uptempo offering with an arrangement based around acoustic guitars. Despite some inconsistency in the material, Killers is clearly the work of a top-notch ensemble, and in order to take the next step forward, their musical ambitions were clearly going to require a vocalist as technically accomplished as the band. It's worth noting that some Maiden fans actually prefer the rawness of the Di'Anno years to the polish of the Bruce Dickinson era (though, it should also be noted, they're in the minority). ~ Steve Huey

KILLERS is based on more straight-ahead heavy metal, departing from Iron Maiden's 1980 self-titled debut, which had more of a punk edge (a facet often cited as an important stepping stone for "thrash metal" years later). Nonetheless the first album was a huge surprise hit in the band's native England, debuting within the Top Five upon release. The group's second release one year later, KILLERS sets its sights on making inroads in America, touring stateside for the very first time. The album was also the first for guitarist Adrian Smith, who replaced Dennis Stratton.

The best-known track remains the renegade rocker "Wrathchild," but other lesser known compositions prove just as strong, such as the gruesome "Murders in the Rue Morgue;" the singles "Purgatory" and "Twilight Zone;" plus the fan favorites "Innocent Exile," "Genghis Khan," "Prodigal Son," and the title track. KILLERS cemented Maiden's standing as one of heavy metal's most promising up-and-coming bands.
