This song pushed a lot of my buttons, a lovely David Gilmore/Pink Floyd vibe to my ears. I loved the sound of the vocal in the left channel that popped in now and again. I can't be more specific because I couldn't really understand what was being said, more a like a cry than a phrase I think, but it sounded fantastic. The melody of the song is haunting and lovely and the changes are interesting and really move the song forward. And I was so happy to hear a guitar bust in when it did. Really nice songwriting and arranging in this piece.
Some subjective comments: I'd love to hear more of the drum and bass working together with a lot more girth and depth, particularly in the break, but I think that's just the rock n' roller in me talking, your laid back drum machine-like treatment sounds a lot like what I hear in more recent pop songs. Still, having the rhythm section unleash at least a little bit at the ultimate moment of the song would add some great dynamic interest.
As to the mix, I agree with pretty much everything that's been said so far about the vocals and bass and I'd throw in the drums as well. Also, I really wanted to hear that tasty guitar jump out and rip a new one, you know, make a stronger statement. The licks are great, I'd just like to hear them much more clearly. This is great work, I wish I could write stuff this interesting and compelling.
