What got me with the first Attick Demons song Travis posted was more the composition and the combined effect of the full band. There's a Bruce-ish voice, but also a good many elements of the music feature decidedly Maiden-ish conventions. If you isolate any of the musicians, you can quickly tell it's not Maiden, but put it all together and they do a darned good impression. If I'd heard that on a radio in the background, having never heard it before, my first thought would be: "New Maiden material?" Second thought would be: "That's not Bruce, is it?" Followed by: "That's not Nicko." And then the guitars have soundalike quality, they even have a pseudo-Adrian - but they don't dazzle.
