I think that is unmistakingly Adrian. Think of e.g. The Wicker Man click here.Who is playing the riff at 10:33?
After the 10.33 riff, they continue with the 9.12 riff and can you hear the difference? Janick does the shorter and imo more consequent short notes and Adrian lays more in certain notes than in others, typically for his style. Here that happens in the middle while @ 9.12 that happens on the right side.
No, these were the horses the airship crashed on.
We're going a bit off topic here but you know what I do not find easy? Who does that melody under Bruce's vocals (during several parts) in The Red and the Black.
At first I thought it was Janick all the time but later I thought of Dave, especially during the Green Manalishi rhythm parts (you know: before we get into the instrumental and The Reeeeed and the Blaaaack parts). The way the guitarist ends every line with some slide of the finger (not sure how to explain it), sounded a bit more like Dave. I like how the guitar continues longer than Bruce. They are not doing the same, at all.
