I'm new here and am also a new Maiden fan. It's been nonstop Maiden for about a month now for me, and I just found Killers yesterday. Right off, the production sounded a lot cleaner and tighter than on the debut, but I'm not sure how I felt about that. The production on the first really fit (especially Paul's voice, which was raw and untamed), so I wish that the production on Killers was a bit more like it. However, the songs were a bit better I feel. I love everything from Wrathchild to Killers, and the rest is pretty solid, too. It still needs to settle for me, but it's a great album that captured my attention much quicker than Piece of Mind did (I only know the first five as of now, and Powerslave is definitely my favorite).
