The great & mighty M.I.A. showed up on Late Night with Seth Myers to perform “Double Bubble Trouble” off her most recent effort Matangi. It was your usual dose of performance-art from M.I.A. with some uninterested folks hanging in the background and a London B-Boy assisting with some fresh dance moves. And, of course, no performance of hers would be complete without some politics, on this night it was “1984 Is Now” scrawled along the back wall. Great song, great performance.
