Classical Organist Robert McCormick performs a stunning improvisation during his concert at Allen Organs’ Octave Hall. Robert was given a sealed envelope with three themes and 8 bars of music from each theme. The envelope was given to him to open just before this segment of his concert. He had no prior knowledge of what the themes would be. Members of Allen Organs’ staff provided the theme suggestions. We hope you enjoy Robert’s improvisation performed on Allen’s G470 Four-Manual instrument!
