I listened to
Long Distance Voyager this afternoon and noticed a few things.
In "Gemini Dream," there's a recurring phrase played between two guitars, one panned left and one panned right. Although the notes that each guitar plays aren't the same (I think the left is a glissando up to G and then two Bbs; the right two Bbs and then a hammer on from Bb to C), I think this is meant to represent Gemini (the twins) in a musical way.
The other thing I noticed is that "long" in the line "First night, so long" is sung with a melisma (G Eb). I'm not sure if this is intended as a description or an interjection of farewell, but if it's the former, there's a musical representation of that length.
