Tuesday, on DCI's Field Pass presented by Zildjian, we got a reminder of how last season ended for Drum Corps International’s Open Class corps as well as a preview of the coming season. This time, Dan Potter chats with three OC corps directors. Each is from a corps at a different stage of development. One is celebrating 25 years in 2015. Another is marking its 10th anniversary and the third is a fledgling corps getting ready to leave its nest in Texas.
