Directed by Donnie Christian, the Lamar High School Marching Band is one of the largest and most visible student organizations on the Lamar High School campus. The marching band performs at all Lamar home and away varsity football games. The marching band is comprised of over 130 students from the three performing band programs and includes students in grades 9-12.
The marching band rehearses daily during school and on Monday, Tuesday, and Thursday after-school. The after-school rehearsal schedule is subject to change due to game days and competitions.
