I especially like that the Irons this time also have the courage to play progressive. Especially the longer titles like The Reincarnation of Benjamin Breeg and The Leagacy benefit from this change in direction. On this album, there is no filler or weaker - more average - titles such as on the previous album Dance of Death.
These songs are never old, because you can see new Facet each time you listen.
With A Matter of Life and Death Iron Maiden is an absolutely timeless work succeeded in that Son of a Seventh Son belongs to me personally, next to Brave New World and Seventh of the three best albums of the band.
