" [laughing] How do you capture sound, like this, it's all about sound with drum and bugle corps, so you're a sound guy and you talked about what a challenge that was.  So tell us about that.  - It's a big-time challenge if you think of an ensemble that has 150 members.  - With an indie budget.  - True.  - Right.  - 150 members in this group: brass, percussion, color guard, and they're on a stage that's 100 yards wide and they're not standing still.  In that last clip, they were doing a standstill performance, but for the most part, they're doing a show where they're moving at high velocity from one end to the other and back and forth.  So that's really difficult to capture sonically.  You see these performances in person and it makes the hair on the back of your neck stand up 'cause it's this wall of sound with extreme dynamics.  You know, symphony orchestra plays very quietly and very loudly, very dynamic, so my co-producer, John JT Torrijos, he actually works with me at Skywalker Sound.  He pulled me aside.  This was probably 2009 into a small home theater room and said, "I just want to play this for you. " He knew my drum corps background and he played a performance that he recorded in Northern California of the Blue Devils and Santa Clara Vanguard, which are competing groups of Madison Scouts and I was blown away by the clarity and how well he captured sonically these performances and I was like, "How'd you do it?" He told me and so I talked to Tom, who is my co-director on this film, and told him that I wish more people could hear the clarity of these kinds of recordings 'cause the typical fan just kind of goes, "Oh, it never sounds like it does live," but this is the closest I'd ever heard, so JT, in a large part, was an inspiration to make the film 'cause we decided that's gotta be a key part of making the film is we wanna capture and reproduce these wonderful, amazing wall-of-sound performances.  - Yeah, you told me earlier that it had never been captured like that before, is that true? - It's true, yeah.  I mean, DCI, the league, does their own recordings and they do a good job, but this was sort of like one step closer, and it really comes down to the mic placement and then also in post-production we did a lot of work mixing the different channels and really trying to make it sounds like it sounds like when you're there sitting right in the middle on the 50-yard line. ECHO is on.
