Regarding the discussion around "The Alchemist" above, I agree with all the praise!
The instrumental break is outstanding and the last chorus, with the "...my world is light, the angels fill my eyes with every breath" and the beautiful reprise of the title track's chorus is one of the best Bruce Dickinson performances, in my opinion.
It's not just the vocal melody, notes or singing technique but the way he seems to put his soul into that performance is truly magical. Alright, part of the glory goes to the brilliant production and mixing of the vocals, but I still say that The Alchemist, maybe overall too, but especially the final choruses, is one of Bruce's most powerful vocal performances ever.
