Okay, so I need an indie/alt rock/any kind of rock style song for an audition for a show with music similar to Spring Awakening

It needs to be about 30 seconds and an a cappella piece

I need for it to show off range as well (its bigger in REAL life, but lets say low A to high A, hopefully hanging around the middle)

Technically, I AM a baritone, but am singing bass 2 in two classes and Tenor 1 in another two. Baritone in none.

I know that I have some SERIOUS competition and there is pretty much only one male role, so I NEED a great piece

Thank You All Very Much
