Before the foursome embark on their international tour in mid-November, the Followills continued their week of late-night “Radioactive” performances with an appearance on The Late Show with David Letterman. While watching the video above, please pay particular attention to drummer Nathan Followill; the dude produces a solid bottom end, provides depth to Caleb Followill’s vocals, and blows a pretty stellar gum bubble.

Come Around Sundown is available now via RCA Records. Video via The Audio Perv.
