I'll echo what Xanandl said, watch anything from the Reading Buccaneers over the past decade. Bobby is a *master* at staging brass and percussion. His work for Bucs last summer was, in my opinion, his best yet. That show was incredibly well designed, without being overly hard (Reading had gotten into an arms race with themselves over the last five or six years, and backed it off a tad for 2016).
His high school drill is also very, very good, particularly his work with Liberty HS in Maryland. I've judged them on a number of occasions, and he always writes with the music in mind.
