Oops,my bad. I got the Woodsoft album name wrong.
I meant the After Burner arrangement in this one

The only information I ever found on this Ges.M was this:

As for Hellion Sounds,I've been reading S.S.H.'s web diary and Twitter since 2007 or so,and other than retweeting the albums releases,I don't remember any mention either.
Also the Hellion Sounds Legacy album has live guitar performance which reminds me a lot of his real guitar performance (The Evil Lord Exdeath and Fighting of the Spirit,compare it to Faraway (you know,the vocaloid one),which I think is the last song he's used real guitar).
