For a band that started out as an unabashed Iron Maiden rip-off, Helloween had matured considerably by the time it released its epic concept album Keeper of the Seven Keys Pt. 1. It ranks as a milestone in the band's career, and sadly one that would never be re-approached. Picture the Yes album Tales of Topographic Oceans, remove the melody and add a lot more distortion. Throw in about 150 twiddly dual-guitar solos and just as many gonad-crushing howls and you've basically unlocked the secret of Keeper of the Seven Keys Pt. 1. As reminiscent of Spinal Tap as the album may be, Helloween's ambition and vigor in an era of stagnancy is admirable and enjoyable. --Jon Wiederhorn
