Sometimes breaks from action outshine the main event, like when commercials make people laugh harder than sitcoms do or intermissions result in more clown-committed murders than operas do. Catch the halftime show without the football game with today’s Groupon: for $10, you get one reserved-section ticket to Drums Across Kansas (a $15 value in advance, or a $20 value the day of the show). The show takes place at 8 p.m. on Tuesday, July 19, at Wichita State University’s Cessna Stadium. Groupon holders will be seated in Sections C & E, and each attendee may bring one sealed water bottle with them.

Now entering its 15th year, Drums Across Kansas is a marching-arts competition benefiting the Starkey Foundation, which aids those with intellectual disabilities, and is sanctioned by Drum Corps International. During the show, eight high-caliber drum-and-bugle corps—including nine-time world champions The Cadets—take the field in competition to mesmerize with crowd with thunderous rhythms. Each major-league marching band delights spectators with the distinctly American sound of wailing brass punctuated by snappy snares, crash-happy cymbals, and loudly chewed apple pies. Aesthetic athleticism and bright bursts of color accompany the tunes thanks to each corps’s auxiliary dance team, who spin and hurl high-flying flags and mock weaponry skyward in boy-band-like unison. Competitive drum-and-bugle corps trace their roots to the traditions of the VFW and American Legion, but today’s DCI corps members are 22 years old or younger.
