Dream Theater:
Solos in "Beyond This Life", sheer speed combined with awkward picking
"Home", "Erotomania" - string skipping
"Fatal Tragedy" Solo, Petrucci doesn't even include the big sweep in there when he plays it live.

Steve Vai:
"Juice" - tapping, and legato.
"Oooo", Speed, plus he doubles it with a clean guitar.


Joe satriani:
"Mystical Potatohead Groove Thing" and "Power Cosmic Pt.2":
it's hard to do that technique, where he taps an arpeggio only with his left hand.
