Stephen Colbert invited the lovely and talented Santigold to perform on his very own StePhest Colbchella festival on the U.S. Intrepid last week. The songstress gave three stunning performances of ”The Keepers,” “Go,” and “Disparate Youth,” all from her Master Of My Make-Believe LP. Santigold was interviewed by Colbert in one of the helicopters that was on display — we couldn’t expect anything less from Stephen, could we? — where she briefly described her journey as an artist, her video choreography and even talked about her guts. (It’s nothing gruesome, I promise.) Check out the interview and her performance of “The Keepers” below. “Go” and “Disparate Youth” can be viewed after the jump.
