At Irving Plaza in New York City last night, Santigold welcomed some special guests on stage with her, including Pharrell Williams who jumped up to play drums on “My Drive Thru,” a song featuring N.E.R.D. and produced by Pharrell. The real show-stopper, however, was when Santigold announced that one of her fans wanted a chance to audition to be a backup dancer. That’s when the ginger-mopped Shy Ronnie timidly walked on stage in a rainbow sweater, ready to strut his stuff to the song “Fame,” a new song from Santigold’s new record Master Of My Makebelieve.
