Maybe I should have put the sarcasm disclaimer in my "Wow" post, as I've seen and heard them, and IMHO it would be hard enough claiming that for DCA, but to include DCI is just plain funny... so, Wow </sarcasm>.
To each his own, I guess. I just don't get them. Never did. I guess many think "book" as in brass only. In which case, it is good, but not so much to stake claim as best in both circuits. For me, however, the generic term "book" includes everything. And in that, not a chance.
More power to those who love them. Just isn't my cup of tea.
This is only my opinion (flamesuit on for the homers), but they are to drum corps what "Drumline the Movie" is to competitive marching percussion. With the disclaimer of THIS IS MY OPINION.
