My hat's off to you, sir, totally ballsy to pull this off. Degree of difficulty adds extra points . . .
There is so much going on in your mix (I can see why this took you a while) that it's hard to pinpoint a comment! I think your vocals work in the Dan style, but the more you push that envelope, the more selective their appeal will get. Which is to say, Fagen won't pay the bills. So what . . . you do a very credible emulation of his style and arrangement!
I think your guitar in spots comes through a bit thin in the mix - I dunno maybe 3:01 area, I'd like to hear those excellent riffs a little louder.
I listened to this three times, liked it better each time. Holy crap that's a monumental arrangement job! Well done, and it reminded me of the Dan meets Rush, with the proggy meter change-ups.
way cool.
