"The Pride of the Hill Country" has a distinguished history. The Texas State Bobcat Marching Band was organized in the Fall of 1919. The Southwest Normal School Band began with support from the Board of Regents, who provided eleven instruments at the expense of the State. D. D. Snow, a student, was the band's first director. He led a group of 22 student musicians who regarded their participation in the band as a pleasant study break. The group first performed at the Southwest Texas Normal School/San Marcos Academy football game on Thanksgiving Day, November 28, 1919. The game was played at the original Evans Field, now the Bobcat Band's practice field.
