From the small clubs of Nashville to London's biggest arenas, Kings of Leon have established themselves as one of the biggest modern rock acts of the 21st century. Now, as they prepare for their first live outings in more than a year, RCA/Legacy will issue the Collection Box, the definitive KoL compendium featuring all five of their studio albums - all featuring bonus tracks previously only available on international pressings - as well as 2009s LIVE AT THE O2 LONDON, ENGLAND DVD.
