Well someone made the point earlier that going first does have the opportunity of setting a standard, and a quality band like Round Rock definitely would have set a great standard, but with a contest of 34 bands, it's quite difficult to stay in the judge's minds unless the show was absolutely phenomenal, which would have been quite difficult given the temperature conditions. In the cold, winds tend to go flat. Vibes tend to go sharp. Vibes are untuneable, and bassoons go pretty out of whack in the cold as well. Generally tuning issues abounded, but overall the band worked hard to keep in tune. The outcome was certainly a well in tune performance given the conditions, but nowhere near perfect, which would also mean nowhere near having an impression lasting the day of 34 bands which included the likes of Bowie and CTJ, especially when those bands perform in the afternoon.
Some kids had the best show of their lives, one saying while he was marching and saw his shadow in front of him, he thought "dang, I look awesome!". The show was definitely the best for most kids, but still wasn't enough to be remembered by the judges and thus lost in the ocean of bands performing that day.
I think it was just the luck of the draw, going first on that terribly cold day, but they played the hand they were dealt, and they accepted the results. Certainly their BOA performance will be performed with the highest level of emotional intensity ever produced from a high school band, no doubt!
