Great opener, both for album and live!
I didn't have anything against those "1,2.. a 1,2,3,4!" or "Aiii!" but I really like certain drama as an opener and this one works just perfect. But... God damn that drum machine at the end of Satellite 15. If I remember correctly, story goes that Adrian brought the demo tape he made who knows when and Steve said - that' it. They didn't even try to produce that in better quality, the thing we hear is as original as Adrian made it. But Kevin Shirley should've forbid that. It just stabs the ear, seems really unprofesional and ruins the Satellite 15.
Bass at the beggining really brings up atmosphere and when Bruce kicks in song elevates on completely another level (he also sounds amazing BTW). But then those drum machines.... FFS that just sounds awfull. The only reason why I can "digest" that is because I know the FF is coming (or when I saw it live, I knew they were behind the curtain waiting to start the show).
Final Frontier is great rock track IMO. I don't get the whole "repetitive" accusation. It's like you bash a trash movie beacuse of it's production value or over-the-top acting/story. Yes, Bruce could've restrain on 2 or 3 "Final Frontier"-s but it's just that type of song and it really works well for me. I also like the "muffled" riff which is again being used in bridge/chorus but this time with a "ring" to it. Solos are amazing, Bruce really nails it and overall it's really nicely bounded toghether. I mean, it's a straightforward rock song to me (as they've probably planned it to be) and I really enjoy the "fluidity" of it.
Both these track still have a kick in it when I listen to them, and worked absolutely marvelous live; as in pumping the atmosphere with Satellite 15, and handbanging and destroying ears of my fellow Maiden fans with the chorus of Final Frontier.
EDIT: Also, the cover for the single also kicks ass. Too bad they didn't continue with the same aproach on the whole album; that would have been interesting to see.
