Since their debut album the Killers have always strived to take a different direction with each album and it works, Hot Fuss was excellent for it's time of release and while some songs were grossly overhyped, tracks like Mr Brightside still shine on today, like rebel diamonds cut out of the sun.
Personally from a fan perspective, Sam's Town is their best, the direction was right for them and almost every track oozed quality.
Now their third main album Day and Age is yet another brilliant direction, not quite as good as Sam's Town but nonetheless decent; the eighties throwbacks are actually quite minimal and if one thing can be said about it, the album is most definitely their most diverse and mostly in a good way.
For me Human, while good is overrated, Spaceman is the track of the album here, back up by suitably solid songs that are A Dustland Fairytale, Neon Tiger and The World We Live In, the rest of the tracks bar one or two are "growers" but overall it's another awesome album from the band.
My advice to anyone wanting to get into The Killers though is to first buy Sawdust (currently £5) which is a collection of the best songs from their first and second albums in remixed form with many other quality B-sides and then purchase Day and Age with an open mind, for everyone else though who knows what they like, get this album and smile like you mean it. :)
