To celebrate the release of her big label debut LP, "The ArchAndroid," Janelle Monae appeared on David Letterman's Late Show last night to perform "Tightrope," which also marked her network TV debut. What a stomping, funkalicious performance that pretty much captures what Monae is all about - great vocals, compelling stage presence, lots of show and a beat to make you move. This would make James Brown very, very proud. Look out for Janelle on The Ellen Show, Lopez Tonight and Last Call with Carson Daily. "The ArchAndroid" train is moving and there's nothing stopping it.
