I have to admit I get a kick out of hearing the UCLA marching band rehearse as I'm walking across campus. There's just something about the sound of a marching band!
I was in marching band throughout high school. I marched flute the first 3 years (including my junior year when, early in the season, I marched right off the field in protest of the band director, Mr. S., who was sexually harassing students, as well as being inappropriate with our mothers. (OK, so I left during the rehearsal right before the game, but it still felt pretty dramatic to me!) We succeeded in getting rid of the scumbag, but it did take the whole school year and a battle with the principal. My senior year, I convinced our new and wonderful director, whose name I am forgetting, that because I'd played organ, I was qualified to join the drum corps playing xylophone. It worked! Not only was I now in the coolest section of the marching band, because our school was poor, we didn't have marching xylophones, only stationary ones, so I didn't even have to actually march!
A few years ago, I was in a piece of Ellen Godena's called 'STATIC isaStateofTelevisionReception'. In one section, we dressed in band uniforms painted white and marched onstage to Nine Inch Nails' "March of the Fuckheads" (if I remember the title correctly. Ellen toured with the Boston Crusaders Drum Corps Colorguard as a teenager, so she shares my nostalgia for marching.
So I guess once a band geek, always a band geek!
