took me 2 *#! weeks to get home, apparently...
I love the song! - I think I'd try some dovetail EQ - it would be time consuming to set up, because you'd need to vary it across different places in the song, but essentially I'm talking about, say, dropping both tracks about 2 db, then cutting 2-4 db for a particular band one one side and boosting for the same on the other, then alternating for the next band up, etc., then resetting the gain on both tracks when you're done. When you've got one side playing and the other silent, you don't want to do this, of course. This could be a stupid idea, but I've had luck with it on guitars to get a wider, interesting image.
Or you could just call it done - it rocks!
