I've been following drum corps (DCI) for 15 years and love the activity. I am concerned that DCI perpetuates a bias when they sanction Michael Boo's blog. Personally, I find it helpful when I am not at a show. However, Boo's blog is one man's opinion -- the only man's opinion that runs on the DCI website. To the extent that Boo writes negative or positive commentary, DCI approves it. We are told that Boo marched Cavaliers for 3 years and has two degrees in music. Does that qualify him to comment authoriatively on the visual aspects? At very least, DCI should sanction a second blog by someone with visual expertise. In fairness to all corps, I think DCI should drop the blog on its website.
