Query: An ambitious, but sometimes overlong epic Maiden album.

Brave New World is better than most comeback albums that bands come back with. Metal bands always say "we're returning to our roots!" or "we're going to really push the envelope and go all out with this!" Brave New World actually does a little of both. Iron Maiden shoots for a very epic sound while using the classic Maiden techniques. Some of the songs are a little slow at some points, but none are bad. These points are what brings the album down to only four stars. Maiden picked up the pace a bit in the two albums that followed though, especially in A Matter of Life and Death.All in all, this is a great album that belongs in any Iron Maiden fan's collection.Personal song picks:The Wicker ManGhost of the NavigatorThe NomadOut of the Silent Planet
