The Cavaliers continued their winning streak tonight in Houston, scoring a 91.55 and edging out the Cadets (90.40), Blue Devils (89.70), Glassmen (84.95), Phantom Regiment (84.50) and the Crossmen (83.85).Approximately 33 percent of Cavalier members are Texans, which made the Rosemont, Ill-based Green Machine practically a hometown favorite. The enthusiastic and young crowd, estimated at more than 4,000, responded enthusiastically to all corps, even after late-afternoon showers left some corps scrambling to get to Rice University Stadium without getting wet. The showers eventually lead to a 30-minute delay before the show began."We were able to communicate what our show was about to a big crowd," said Cavaliers' corps director Jeff Fiedler, who also noted that the Cavaliers had spent a decent portion of the previous week tweaking the show in the Dallas-Ft. Worth area. Fiedler added that the Cavaliers would still continue augmenting their show through the summer. "It's nothing we can't make better," Fiedler said of the Cavaliers' program, entitled "Frameworks."The series of Southwest summer showdowns continues Saturday in San Antonio, Texas, in a show that features many of the same corps (the Phantom Regiment, the Cavaliers, Cadets, Glassmen, Crossmen and Blue Devils) alongside the Santa Clara Vanguard and the Bluecoats. The Santa Clara Vanguard will lead a clinic for students in the afternoon. The Cavaliers' innovative show is continuing to excite crowds, parfticulalry large ones like tonight's, Fiedler said. The entire Cavalier show is based on a single melody, which is getting increased prominence after some mid-season rewrites. Two "frame" maneuvers -- a cumulative block box and a formation where the horns surround the guard and break into an enthusiastic jig (a section of the show referred to as the "Fight Club" by Fiedler and the Cavaliers' staff, a reference to the 1999 film starring Brad Pitt) – continue to be crowd-pleasers. Prior to the contest in DeKalb, Ill., last weekend at a Drum Corps Midwest contest, the Cavaliers spent a week tweaking the show. Fiedler said the corps dropped the last three charts of the show and added a smaller re-enactment of the "Fight Club" sequence to the ending then. The Cavaliers dubbed this final sequence "Operation Mayhem," yet another reference to the film. "The new ending basically recreates the frames (section). We extended the ending to make stronger statement about frameworks at the end," Fiedler explained, adding that the entire recreation happens at the blistering tempo of 204 beats per minute. The Cadets show, meanwhile, is receiving many positive responses as well. "We're getting a lot of reaction from the fans. We're tearing down houses across the country. It's been one of my favorite years so far," Cadets corps director George Hopkins said of the 2002 season. The corps extensively tweaked its shows on July 8 and July 9, during which approximately "two-thirds" of the opener was "completely changed," according to Cadets guard member Wendy Stone. Corps director George Hopkins said that the Cadets "changed 2 minutes in two and a half days" – a monumental change. "We were petrified we weren't going to get it done in time," Hopkins said. The original design of the Cadets' opener was broken into three sections that ran approximately one minute too long, Hopkins estimated. He, Cadets drill designer Mark Sylvester and other Cadets staff members then worked to break the three sections of the opener into two sections, all of which are set in the 1940s in New York City.
