Kings Of Leon Debut New Song, Video!

Just when you thought that they couldn't get any worse.

Kings of Leon have finally given their fans a taste of their new material with the song, 'Radioactive,' which debuted Tuesday on the radio and as a video. The track is the first single off the band's upcoming fifth album, 'Come Around Sundown,' which is due out Oct. 19 in the US.

The gospel-tinged track is a mix of the band's earlier southern rock influences with the streamlined sound of their Jacquire King-produced 2008 breakout, 'Only by the Night.' To reinforce that back-to-basics notion, the sepia-laden video shows the Followill clan performing the song in a barn, hanging out at a southern luncheon and rocking out with an African-American children's choir. Check out it out after the jump.
