The 2004 Drum Corps International television broadcast will begin airing around Labor Day in most markets. The PBS broadcast is most folks' first introduction to the wonderful world of drum corps, and initiated drum corps fans also know to tune in. "Drum Corps International has enjoyed a special relationship with the Public Broadcast System since 1975, when the first DCI World Championship was broadcast. That was my first year of marching in a corps, The Cavaliers, and back then, the broadcast was live. All my friends knew to watch it, and in doing so, I wouldn't have to explain quite so much just what drum corps was, and what it wasn't," says drum corps historian Michael Boo, a columnist.
