Good reference point in regards to Big Black, there definitely is a Big Black vibe in your music. Whether this is intentional or just 'part of the inherent energy' is of course up to you to figure out. How do you believe that Gang Of Four is an influence on your music? Which aspect of your music is informed by Gang Of Four's musical style?
EDIT: I guess when you come down to it, you guys sound like yourselves; and that's always a good thing.
