This song has my favourite vocal melodies, from the whole Maiden catalogue. When Bruce starts singing "Even though it's reached new heights" I am totally under some kind of spell. One of the best parts ever!
It's not just the singing, it's the combination with the music underneath. From the first seconds of this song Nicko plays his instrument with delicate feel, but in this "Even though" part he goes into a stimulating groove, together with good old 'Arry. The keyboards make it all richer and between the chords Adrian does this nice melody. What's also cool about this part is that it is a slower part than the previous one. I think this is pretty rare for Maiden, definitely when it's early in a song, and I feel it certainly makes it the more special.
Later on, Adrian and Dave play some nice harmonies. The one starting at 4:02 is one of the very best guitar harmonies in the world of music (check that gallopping bass underneath!). The solos are very nice, with piercing high tones. The way Adrian ends is really cool.
The lyrics are quite intruiging as well, so is the pretty unique atmosphere. For this well constructed melodic masterpiece I can't give a grade lower than 10.
