September 16, 2026 — The energy and sound of high school marching bands will once again fill the air this October as talented student musicians from across Cobb County come together for the annual Cobb-Marietta Marching Band Exhibition.

For more than five decades, young musicians have demonstrated their collective talents at the annual Cobb-Marietta Marching Band Exhibition. Musicians from across the county will celebrate the 53rd year of the band exhibition with performances on the first two Monday evenings in October.

After enduring the heat of summer, with months of rehearsals, practices, and overall hard work, Cobb's marching bands will take the field for two nights of performances. The 2026 exhibition will be held on October 5 at Harrison High School and on October 12 at Lassiter High School.

The exhibition is a chance to experience the energy and excitement of marching band season while seeing the creativity, musicianship, and dedication students bring to the field. For the participating bands, the event is the culmination of months of preparation and an opportunity to showcase their performances alongside other talented musicians from throughout the community.

The Cobb-Marietta Marching Band Exhibition has been a cherished local tradition since 1972, giving generations of students the opportunity to perform and audiences the chance to celebrate high school marching bands from across the area.
