Callahan

I'm no good at writing review-ish type things on bands. But I can tell you that Callahan are probably one of the most underrated hardcore bands in the scene right now. They're all badasses and decided to define their sound as "applecore" which certainly does bring the lulz.
They've done about 5 cross-Canada tours, and a few short tours in the states.. Which is pretty good for a small band from North Vancouver.
