Emrick stayed on as full-time director after his graduation in 1908. In 1921 Emrick commissioned the Leedy Manufacturing Company of Indianapolis to construct the world's largest bass drum. The "Big Bass Drum" has been a part of the marching band ever since. In 1935, during a Purdue football game at Northwestern University the band donned lights on their uniforms while performing at halftime. With the stadium lights turned off for the performance, the band drew such awe from radio broadcaster Ted Husing, he referred to them as a "truly All-American marching band," hence the current title of the band.
