Andrew Nemr has spent decades closing this gap; as a professional tap dancer – performer, company director, and educator.
He was mentored by Gregory Hines, Savion Glover, Jimmy Slyde, Henry LeTang, and Mable Lee, and applied what he learned in the studio, on the stage, with his company, in his band, on recordings, and in film.
He didn't arrive at this work from another textbook. He came back from the road with it.
