What about a little bit of Malmsteen ?

[Sharuru]

of course he's done a lot of crap and he got a serious ego problem, but that being said he has been a part of the neo-classical mouvement, and has some really proggy tracks, putting aside his ability on guitar.

Of course if you don't like light-speed guitar playing, that's a problem but...

And personally, I prefer a lot M Romeo of Symphony X, but this guy is heavy and doesn't fit to AM (ballads would do it although).
