Frederick seems like a solid pick. He's had some good success in UIL marching. Concert and sight-reading results are solid, too. I don't think Jersey Village does much BOA. I'd have to check. But the wall between the stereotypical "UIL-style band" and "BOA-style band" is fast dissolving anyway. And it's not like that Bluecoats/Blue Devils design team is going to write a show that isn't fairly contemporary, assuming they stick around.
There are so many staff changes underway in Texas. Somebody needs to compile a concise list. This season is shaping up to be a very fascinating one!
