Dig the whole spirit of the tunes! Super vibey, right up to my taste. I can hear the YES influences, not the Anderson tone, but the phrasing in places. But also Styx, deep-cut Ambrosia ('Rich Boy Poor,' 'Nice Nice' etc), A little Zeno Roth, Peter Gabriel, early 80s prog. Very Enjoyable!
As for the 'mix,' performances aside, it feels small and 'demo production' congested. But the energy and performance are there, and that is the most relevant! I understand it is a mix in progress!
Look forward to more.
[edit] Sorry, Robert, I didn't see the 'feedback on the mix' request. In my experience, 'smallness' or 'demo production' is a result of congestion. Too much shard space. Since I don't know what this was recorded on or if there were old-school restrictions, bounces required, etc., I don't know the limits of your gear. Or your monitoring. So forgive that! You have 4-6 guitar tracks at once (which include 'rock' acoustic), doubled and layered vocals (and a talking octave vocal at times), a lot of constant lead lines, and bass (played with a pick it sounds like) and drums. In my listening environment, so much of the energy is shared and focused in the mids and down the middle. The drums get lost for me, but the irony is that is one of the elements that remind me of an era.
Obviously, track count and stacking are no problem, but I think working on the track/instrumentation separation and moving the drums forward will go a long way.
The approach to do that, is individual. Personally, I start with drums and then make space for vocals and harmony instruments with frequency separation, not pan-width only. For your style of tunes and tones, albums like Paradise Theatre, The Grand Illusion or even The Point Of Know Return are great references and models. Albums with great separation clarity but mid-forward tones and production restrictions. Again, great tune!
