This is Maiden at their very best. Bruce delivers an amazing vocal performance with godly high notes, and some of my favorite solos from Murray and H ever. The crushing verse riff at the beginning built from the harmonic minor scale really conveys the Egyptian atmosphere of the album, and did I mention Bruce's vocals were godly? Following the verse comes my favorite part, the instrumental middle section. Love Steve's bass in this, and the counterpoint between the bass and Davey's legato solo is beautiful and almost neo-classical sounding. H's solo is eargasmic as well as Davey's following. Nicko's fills are fantastic.
I could keep going on about this, so I'll just say 10/10, most certainly the climax of the album.
