Kings of Leon have risen to the rock and roll firmament with alarming speed. Just a few years ago they were a band of brothers (and a spare cousin) kicking around the backstreets of Nashville, Tennessee.

And now? Now they're so big that they've got their own app, courtesy of music bible NME. Built by Umee - who else? - the NME Kings of Leon Wallpaper App features classic images of the band so fans can personalise their iPhones.
