Cool stuff. It has texture and personality. Seems to me you guys are evolving a sound of your own.
I like the way it's all kind of a loose pastiche through the verse section, then comes into sharp focus for the chorus.
Chorus reminds me just a bit of the band Ivy (RIP Adam Schlesinger); it's very easy to imagine a breathy female vocal over it.
Is this project intended eventually to have vocals?
Verse sections might need to be a little sparser to serve as a bed under lyrics.
But the transition from complex/slightly chaotic in the verse to simple/congruent in the chorus is very nice indeed.
I really like that.
Also liking the G Major that leads into the chorus - nicely foreshadowing the G Maj that the chorus finishes with.
I love the almost-but-not-quite-resolution of ending a part on a major II chord.
In the verse section, I found myself wanting to hear the chord progression more clearly when the slide is going off on its own.
Was going to suggest bringing up the rhythm guitars a bit in the mix, but that would take away from the slide part.
What if the bass followed the chords once the keys and slide come in, rather than playing an F through the whole section?
That would reinforce the progression without needing to change the balance.
You could use a low F note on the keyboard to maintain the same kind of pedal-point tension.
Nice work there. Please keep sharing with us as your collaboration progresses.
