In addition to the wonderful championship studio recordings (5.1 Dolby surround sound and Dolby surround sound versions are included here) and the entire world championship show from Madison, Wis., (and a sideline camera presentation), the commentary of the staff and members of the Blue Devils on the corps' 2002 DVD "Inside the Blue Devils" offers terrific insight to the rehearsal mindset of a top corps as it evolves through the summer.The professionally rendered, behind-the-scenes documentary included in the package offers a raw glimpse at how a corps can adjust and augment almost an entire show through the course of the summer and still achieve excellence."The corps this year has, in fact, learned two shows," Blue Devils' marching instructor Ken Karlin says at the beginning of the documentary portion of the DVD, which was produced by Rob Weiss.Hard core drum corps fans will love the raw, unnarrated rehearsal segments that featured the drum line, brass line and color guard. Meanwhile, guard captain Jessica Allen's segment of this year's PBS broadcast is included in its entirety on the DVD.This DVD is a great additional purchase to the 2002 DCI World Championship DVD, which you can buy HERE.You can purchase "Inside the Blue Devils -- 2002 DVD Special Edition" HERE.
