The slogans "With Tradition Unsurpassed" and "Play like a champion today" describe the Southside Band Program in both its past accomplishments and present endeavors. The 180 students of the Maverick Band share a bond with all past band members in living up to this tradition of outstanding performance and character in all areas of the band program. The band members strive for excellence in several performing groups: the Maverick Marching Band, three Concert bands, and the Jazz Band. In addition, numerous ensembles (percussion, brass, woodwind, etc.) perform throughout the year.
The Southside Bands are known across the state and region for producing outstanding individual musicians as well as exceptional performances by the marching band and all three concert bands. Since Southside opened its doors in 1963, the band has had over 3100 positions in the all-region bands, 256 in the all-region jazz bands, 1008 seats in the All-State Concert Bands, and 83 in the All-State Jazz Bands. The bands have also earned the ASBOA Sweepstakes Award for thirty consecutive years of having earned first division honors in marching, concert, and sight-reading adjudications.
The Southside Band has traveled many places and been goodwill ambassadors for Southside and Fort Smith. The Band has performed in Hawaii, New York, Chicago, Indianapolis, San Antonio, Washington DC, Orlando, Kansas City, St. Louis, Houston, Nashville, Hot Springs, and Gatlinburg.
