It's a toss up between Flight of Icarus and To Tame a Land, but I'll go with the former. This has recently become my favourite Maiden album, so I wouldn't mind hearing most of it (or at least, more than usual) on the upcoming tour.
9/5 - Spell/Manacle
9/6 - Crimson Shadows CD Release Party
10/17 - Satan
10/18 - King Diamond
