I'm also curious what is believed needs to be improved in the brass arrangement - I've enjoyed Ryan George's music over the past few years - it seems to fit the BAC style. Also, I seem to remember only positive comments about BAC's music this year. The only negative comments (besides those from the anti-vocal, anti-synth clans) seemed to be focused on the visual and show design this year.
Although it took a while to hit its stride, I thought this year's show design was pretty spectacular during the championships, and fitting of a 75th anniversary extravaganza. Maybe, it could have spread the field or worked around the banners a bit more - who knows. I'd be interested in what the GE judges had to say about it during the season.
BAC had fewer competitive shows scheduled this year, and one of those was a rainout - while this gives them more time on the practice field (also more time for the designers and staff to make changes), I wonder how much effect this had when they were competing. Does this help or hurt their mental confidence when they're performing?
