AUBURN — The Maine Band Director’s Association will hold its 20th annual Twin Cities Marching Band Show at 6 p.m. Saturday, Oct. 16, at Walton School, 92 Mary Carroll St. The association’s schedule consists of five regular season shows and the Maine Marching Band final which is held in November.

All events are rated against an established standard of performance excellence. Each band performing receives ratings based on general effect music, ensemble music, field music, general effect visual, ensemble visual, field visual, percussion, color guard and drum major performance.

Ratings are based on a five-star system, with one star being the lowest rating, and five stars being the highest rating. Marching bands compete against the established standards rather than each other.

The performances will vary with a wide range of themes from big band swing to a tribute to the music of John Williams. Seven high schools will perform, including Edward Little High School and Leavitt Area High School.

Admission is $5 for adults and $3 for students and seniors. Proceeds will benefit the ELHS music association. Concession service will be available.
