Sonata Arctica: black sheep
Sonata Arctica: san sabastien (actually a keyboard solo but damn crazy to play on guitar!)
Eric Johnson: live austin city limits version of cliffs of dover (the improv at the beginning is absolutely astounding!)
Dream Theater:As I Am
Wuthering Heights: longing for the woods pt.2 the ring of fire.
Wuthering Heights: Bad hobbits die hard. (nice russian sounding instrumental absolutely insane to learn)
and bassically any keyboard solo transcribable to guitar by any richard ansersson band.
