Expert theremin playing is never not awesome to watch, and few were as masterful at it than Lithuanian thereminist Clara Rockmore. Not only is her performance of Camille Saint-Saens' "The Swan" stunning in its weeping beauty, but Rockmore herself is a transfixing watch, never changing her stoic demeanor or looking even the slightest bit impressed at her obvious virtuosity. B.T.W., her sister is at the piano.
