Honestly, I've had several kids who missed their concert. I yell like there is no tomorrow. They let not only me down but their peers down as well. Your band Director will yell at you and make an example of you. He/she will never trust you again, and you will be on their bad list.

To the other person who posted, its not just band. They work all semester long just for that concert to showcase all the hard work theyve done. Clearly you dont understand and you never will, waste of time.

Why don't you just ask your teacher and it can't be that bad it's only band.
