Even without Big Boi, who guests on Janelle Monae’s new single from her album The Archandroid, Monae performed a ridiculously awesome rendition of “Tightrope” last night on Letterman. The performance included costume changes, an awesomely synchronized guitar and bass duo, and incredible presence from Monae herself. Say what you will about her hairstyle, but she’s bold and ready to make a huge splash in the pop world.
