[Watch] The Flaming Lips - "Look...The Sun Is Rising" Live on Letterman

Last night if you follow us here at SKoA closely, you may have been aware that Kibbe was at the Ed Sullivan Theater helping Wayne Coyne with his Reddit AMA prior to the band hitting up Letterman. You can check out the interesting AMA over here if you missed it. Chances are if you missed that, you may have also missed their performance on Late Show with David Letterman so why not hit play on the video above to see Wayne and co perform "Look... The Sun Is Rising" which is taken from their forthcoming album The Terror. It comes complete with Wayne cradling a toy baby throughout the performance... yeah. Standard Flaming Lips, really.

That's not all the Flaming Lips goodness this week. Some of you may remember Coyne and co. teamed up with Bon Iver on a track for last year's The Flaming Lips and Heady Fwends. The collaboration, titled "Ashes In The Air", now has a video and it's as weird as you would expect. Check it out below.

[Watch] Wavves - "Demon to Lean On" Live on Letterman

Last night Nathan Williams brought his depressing yet catchy tunes to late night telly with his band Wavves. Bringing along a performance of "Demon to Lean On" to the Ed Sullivan theater and the Late Show with David Letterman the performance was raw and on point. The track features on the newly released album, Afraid of Heights. When the guitars are left to let rip this performance rocks, but I'm not quite sold on Nathan with minimal backing, maybe it was an off day. Still rather enjoyed it though. See what you make of it above.
