I've always thought BD should do a Dizzy Gillespie big band show, playing stuff from his Afro-Cuban repertoire. I'm sure they would need to put some storyline to it, so as to please the judges: "Tales of Havanna", "The Cuban Chronicles", or "We Don't Need No Stinkin' Amps"..... Who knows.
Also, an all Charles Mingus show would be killer for the Blue Crew. If the Devils don't want to do this stuff, I also know of another blue team from Ohio who would also do a wonderful job with this material.
SCV or Regiment should really explore Prokofiev. The 5th Symphony has some great drumcorpsesque moments in it. Someone also mentioned Romeo and Juliet, also an excellent choice.
