Kings of Leon, 'Radioactive' -- New Song

Kings of Leon seem to be living up to their promise not to play it safe on 'Radioactive,' the first single from their upcoming fifth album 'Come Around Sundown.'

The record is the much-anticipated follow-up to the 2008 breakthrough smash 'Only by the Night,' which introduced the band to millions of new fans with a pair of maybe too-easily digested and overplayed singles, 'Sex on Fire' and 'Use Somebody.'

'Radioactive' announces the band's somewhat experimental intentions right off the bat, as a distorted, woozy bass line and an almost progressive-rock flurry of jumbled guitar notes leads into the uptempo, percussion-heavy musical track.

Caleb Followill's distinctive, soulful vocals soon arrive to help keep things familiar; and as the song builds -- in more typical Kings of Leon fashion -- to a big, hummable and uplifting chorus, he and his new-found female backup singers address the importance of tradition:

"Its in the water, Its in the story of where you came from / Your sons and daughters in all their glory its gonna save her / And when they dance and come together and start rising / Just drink the water where you came from / Where you came from."

'Come Around Sundown' will be out on Oct. 19. Kings of Leon will wrap up their summer tour with a hopefully pigeon poop-free show on Sept. 25 in St. Louis. Check out 'Radioactive' on AOL Radio's New Alternative First station.
