We are offsetting the front ensemble this year for a few different reasons. We have several moments happening at the center of the field (ie. when Anna freezes the band at the end of part 2) and the front ensemble would have covered them up. Another reason is that it gives some exposure to the front ensemble, that they wouldn't normally get, because they are usually hidden behind the conductors podium. And probably the least important reason, is that it is away from the norm and will potentially get people talking and kind of a buzz going.
Many bands are doing different set ups with the front ensembles. Last year, defending Flight IV State Champion Godwin Heights had the front ensemble at the back of the field, and BOA Grand Nationals Finalist Marion Catholic had their front ensemble on the field on Side 2 set up in "rock" props for their underwater show.
