I have both Iron Maidens CDs. I love listening to them. I have several Iron Maiden CDs and love listening to them too.
When I come to your shows, however, I don't come to hear music that sounds just like a CD. I come to your shows to hear live music, and see, hear, and feel the energy of live music that can never fully be captured on a CD no matter how high-tech the engineering or recording equipment. And Alexander, as Paul said, does kick major ass each time I've heard it, and each of you deserves credit for making it so.
If you can manage to bring in keyboards, great.
But for God's sakes please don't make it sound just like a CD!
