This cartoon band created by Damon Albarn and Jamie Hewitt in 2001 is embarking on a tour with performers in front of a screen showing the cast of characters—last tour it had them playing behind it to keep the guise going. The David Letterman Show hosted the group on the eve of its gig at Madison Square Garden for the “Live on Letterman” series Friday, October 8th as a lucky audience witnessed one incredible dress rehearsal. The camera goes back and form from cartoons (loved the children’s choir) to musicians while they dug into the playlist. The first song, “Kids with Guns” off of Demon Days got the funky groove going before the band lashed into newer tunes off of the new CD Plastic Beach. Some weird feedback had Albarn apologizing but who could complain? By the time the hits were rolled out for the closing, “Feel Good Inc.” and “Clint Eastwood” almost half the audience was on stage—since it was practically on crowd level things were just too tempting not to start a dance party. The non-dancers stayed in their seats hardly moving, making for an interesting juxtaposition indeed.
