Megadeth - Hangar 18, Lucretia, and Tornado of Souls
Nevermore - 42147 and Ambivalent two awesome solos by Loomis.
Demoniac - Demoniac Spell - Some hilariously crazy guitar playing...
Jason Becker - The whole album Perpetual Burn is obscene
Yngwie - Black Star, Far beyond the Sun
Friedman - Anvils, Saturation Point, Forbbiden City
Van Halens - Eruption is pretty crazy for a solo piece
Morbid Angel - Hymn To A Gas Giant, Chambers of Dis, Azagthoth <--funny as hell and insane; Secured Limitations
Death - Scavenger of Human Sorrow, Overactive Imagination, Voice of the Soul owns me.
That's about it. There are tons of awesome guitar solos. My favorite out of all those is still Perpetual Burn.
