Weekends between September and June are crazy for me, so I do not get to see too many high school band competitions, but I know King Philip in Wrentham, MA has an excellent marching band and its shows are designed by Ed Devlin. Dartmouth High School has a good marching program and has a WGI presence. I know folks who either are or have been involved with Dennis Yarmouth (on the Cape), Jordan Case (Swansea), Melrose, and Mansfield who say these schools strongly support drum corps. A non-school all age band from the Cape, Spirit of America out of Orleans, has an excellent brass choir, a WGI champion percussion ensemble, and has had some members march with Cadets, including a young man who was one of Cadets top soloists. Then there are also the schools that have excellent music programs but do not have as strong a marching component, especially the private schools, Catholic schools, and charter schools. The talent exists, but it's largely untapped.
