Not to be outdone by Deerhunter’s Fallon appearance, The Flaming Lips stopped by Letterman last night to deliver a whole new definition of weird. The band performed “Look…The Sun Is Rising” with their creepy, futuristic stage design while eccentric frontman Wayne Coyne caressed a baby doll. It’s out there, but then again, this is The Flaming Lips. Let it haunt you above.

The band also revealed in a Reddit chat that they are planning a collaborative album with Ke$ha, stating “SHe is a blast on all levels. She’s funny, she’s humble. She’s badass. She’s everything. She’s awesome. We’re actually already working on an album with her. It’s called Lip$ha.” So, there’s that.
