If you mean what original & creative thing has drum corps done that has gone beyond the bounds of the idiom?
Nothing.
Nothing wrong with that. Drum corps is great. Just not popular.
I'd go & watch, but I don't want to deal with all those #### people hanging around.
I'm having Thanksgiving dinner at my place in Brooklyn--ya'll should stop by after the parade!
Scouts --Rosander on drill, plus the return of many horn vets, plus the highest finish since '99
Bluecoats --of course
Southwind --made semi's for the first time since . . . '00?
Phenomenom of Cool
The Carmen Project
Inventions for a New Millenium
For the most part, I think pretty cheesy & too overtly trying to be 'artsy.'
edit: those three are three I actually enjoy. The vast majority of show titles are quite cliche.
I can guarantee you that Marian and Plymouth and Center Grove and those of that caliber are not importing drum corps shows, nor are they imitating corps. They're much, much different than corps, but with equally as well-designed shows.
bit off-topic: I took a flag to the head at the Canadian Open in '00. Bled all over the place (uniform, field, flag, others, etc . . . ) and finished the show with a smile. Didn't hurt, though--that was the strange part.
BK '03 is a great show to listen to. 'Kavil Sviri' especially is great--so dark up until the end, then it just opens up.
That show and Southwind '00 are my two favorite non-top 12 shows ever.
