Allright, let's hear these new songs!
Hero's battle:
Overall I like the electro-orchestral and metal combination that makes this piece flirt with what we can hear in some modern-era jRPGs.
The intro effectively builds-up the right kind of atmosphere, so when the song kicks off, we definitely know we're in for one epic battle.
The composition, while softer compared to some of your other works, is flowing nicely, with a consistent sound and a good amount of variety.
It's evenly paced with frequent breaks, leaving room to breath and keeping the song from being stuck into a repetitive pattern.
The guitar is once again the star of the show, with those fierce and eloquent solos, unsurprisingly being the high points of the song.
The melodies played by both piano and synth work well with the guitar parts, toning down the metal a bit, but creating the right balance in soundscape.
However, I think the piano (or/and harp?) sequencing is bit rigid, requiring some humanization work in your part.
Also, are you still using the DFH kits? That snare sounds pretty dead center and dry.
It's especially annoying in this song since the track has a more atmospheric approach, thus needing reverb to build the proper ambience.
The Discovery:
It's a rather disturbing piece, with an unsettling composition, and use of dissonances.
Those guitar chugs mean business! They really put emphasis on the already extremely dark tone by adding a tangible feeling of wrath and rage.
I don't have much to criticize, except maybe for my usual "snare drum complain", which by now sounds more like a personal bias than an objective critic.
Other than that, nothing production-wise annoying enough to spoil the listening experience of someone who would enjoy the song's composition.
Not digging this particular piece as much as usual, but my opinion doesn't remove anything from your performance.
And from what I'm hearing here, that certainly won't prevent me from looking forward to your next album.
Keep on rockin' Joe!
