* This is an official 2017 NGUAC review *
Oh yeah, one of my favourites! Really cool, innovative piece of music. On to specifics...
Mixing, mastering and production: The most impressive thing to me with Market Day is the number of sounds you weave together successfully. I've commented on some other submissions how they have an 'everything but the kitchen sink' syndrome, where they attempt to use tons of different instruments, but it ends up sounding like a mish mash blend. You've used an eclectic but very effective group of instruments and made them work together.
From a production standpoint, having many different types is tricky and mixing them together is no small challenge. There are some issues here, particularly in the synths. The tricky part is that most of Market Day is grounded in real instruments (or real-sounding instruments) which means the obvious synths are always going to be the odd man out. Therefore, they have to be mixed really masterfully in order to fit in (as opposed to just another orchestral instrument, which you could plop in and it would fit more effortlessly)
The synth bells at 2:05 are pretty tinny and cut a little painfully through the mix. The bells at 3:18 are much better, but of course they're not TRYING to be a synth effect so much, so they fit in better.
There are some other points where I can tell pretty obviously I'm listening to a virtual instrument. Some of the violin lines, the acoustic guitar, and some piano bits especially. The best answer here is to actually record those instruments, but in lieu, one thing you can do is pay very close attention to editing the velocity of the MIDI files that the instruments are playing. When a pianist plays a piece, they're not going to press every key with the exact same amount of force. They sweep, certain notes are louder, and perhaps just as important they ARE NOT ALWAYS ON TIME (I wish I could italicize). If you're aiming for a 'real' instrument feel with a virtual instrument, know this: nearly zero musicians have perfect rhythm. So a 'real' instrument recording would reflect that. Just little tiny 'errors' here and there would improve the realism of an instrument line.
Good use of EQ, good use of panning, and for the most part good volume balancing. Very clean mastering as well - I only feel like it could have used a bit more umph. The kick drum and the orchestral bass drum were sort of underwhelming. There could have been a little more bass overall.
Composition: Awesome. Great chords progressions and very smooth changes between keys, not to mentioned tempos. Heck, if you had switched through time signatures as well you could have had the trifecta! I have very little to say except for very minor things. I enjoyed the structure and progression, but at the same time it wasn't inherently catchy, which is as valuable as a well-thought structure. The lack of distinct repeated main sections (there are two distinct instances of the chorus, but as they're in different keys there's still a degree of difference between them) docked half a point or so from the structure.
My same critique would extend to the melody. There are lots of interesting, well-thought out melodies in Market Day. But sometimes, all you want to hear is one really solid one repeated a few times so the listener can appreciate it. A little bit of structural repetition would solve this.
Overall, really great piece. I'm super looking forward to what you'll come up with in the finals.
