I caught this at the preview show and was heavily impressed. I try putting together a lot tune every year for my students, but this goes above and beyond! It's awesome that you put in the time to actually make this a reality and hats off to the front ensemble for caring enough to put themselves into this epic performance piece!
Make sure to get a head start finding what you need for the audition process, save up money to do so (roughly $5000), watch RU-vid videos for technical details (or better yet, try to get instruction from members or technicians from the desired corps), PRACTICE, and most importantly, come with a friendly, positive attitude. Don't take not being accepted to your favorite corps negatively, it is just another learning opportunity for you.
