You guys have a great idea of the ska/punk thing. LOVE the subject matter. I miss those damn things. Anyways, in my humble opinion, I think you are a little guitar heavy and a little vocal light.... but the spirit and the energy are great. Nice.
I never really listen to ska very much to be honest, but this raised a smile - great upbeat song. Love the heavy guitars and the brass. I would have liked to have been able to follow he lryics a bit more though - I can't make them out very easily.
the intro was funny. It seems like you've found a talented group of guys (i'd like to know how big a band it is). All the vocals needed was volume, but not from the mixer, just let it out man! Yell once an a while, it's punk!
