Well some bands are good or very good, but they all have their "jewel" (beauty lies in the eye of the beholder of course

) here's my take :
Vai : Passion and Warfare
Satch : self-titled album
YJM : Rising Force
DT : Images and Words (and Tokyo DVD)
Metallica : ... and Justice for All
GNR : Appetite
Adrian Legg : Guitar for Mortals
Extreme : Pornographiti
Ben Harper : Burn to Shine
Jan Cyrka : Spirit
Jimi : Are you experienced
Loreena McKenitt : The Mask and the Mirror
Megadeth : Rust in Peace
Pink Floyd : A momentary laps of Reason
Rage against the machine : self-titled album
Van Halen : 1984
Vinnie Moore : The Maze
Tracy Chapman : self-titled album
U2 : Achtung Baby
IA Eklundh : Freak Guitar
not in any order and I'm sure I forget alot of stuff I like.
What's your list ?
