I love the concept, it's a very interesting fusion of a hip hoppy beat and brass instrumentation on top. The samples sound quite lo-fi and harsh, so unless that's the intention, this song could benefit from higher quality samples (most of it is fine, really, the trumpet first heard at 0:09 just makes a bad impression).
The arrangement is nice, very different from most compositions heard at NG, the instruments complement each other nicely. Most of the instruments tend have very repetitive themes though, after a while it all sounds like one big rhythm section. Something like an acoustic guitar solo would be a welcome melodic addition, which would probably fit perfectly with the style of this track as well.
Looking forward to a finished version of this, please pm me if you finish it because I love the idea
