This is an NGADM Round 1 review.
I am left in absolute awe. You had all the odds against you and made something that is definitely one of your best works, spanning over 8 minutes of incredible jazz music with wonderfully-fitting funk influences. There's a superb amount of variety in this track but everything is still structured so well, with well-executed crescendos (like 2:22 onwards which has the most beautifully subtle sax introduction ever at 2:35 may I add) and even a reference to the beginning melodies towards the end, truly bringing everything into a full circle. And the production, the one thing which I was worried about in your track, is actually very good! There are a few inconsistencies, like 6:52's piano not sounding nearly as crisp as it did at the beginning, but overall everything is produced well! Not as clean as it can possibly be, but certainly very good.
I feel like an idiot pointing out flaws in such an incredible track, but really all I could find is that sometimes when a lot of instruments play together, the result sounds a bit messy and sloppy (1:43 for instance). In fact, the points where you've got a more controlled and manageable amount of instruments playing, the track sounds so much cleaner in all. This could be due to little rehearsal time or lack of detailed audio editing work. Your ending is a bit lame for such a long and developed track as well.
Those are all the flaws I can think of without obsessing over this track for hours to look for the tiniest nitpicks imaginable. This is absolutely brilliant and I'm thoroughly impressed.
