In 1992 Holsinger — himself a former marching band director — spent time with the Cadets to help them understand the music they were portraying with To Tame the Perilous Skies (2nd place).
He then provided the compositions for the Cadets' 1993 gold medal win with In the Spring, at the Time When Kings Go Off to War, Ballet Sacra, and On a Hymnsong of Philip Bliss, defeating the Star of Indiana Drum and Bugle Corps by only one-tenth of a point.
