Wow, many of my favorite albums listed here. And it's always great to see Chris Poland appreciation as well, awesome player and to me at least he has a very original sound and style!
A few of my favorites in some kind of "finding" order:
Vinnie Moore - Mind's Eye
A school mate of mine gave me a tape with this as the main album. I remember how I couldn't get over the sweeps and melodic style of playing. Played the tape every day before and after school, for the obvious reasons and something more that follwos:
Joe Satriani - Surfing with the Alien
This album was on the same tape with Mind's Eye as some sort of leftover. What a hit this combo was to a 13 year old aspiring guitar player! I fell in love with shredding with these two albums!
Vinnie Moore - Time Odyssey
I remember when this one came out, I just had to have the vinyl no matter what the cost and I played it over and over and over and tried to learn at least some bits of the songs...failing miserably every time

. Later years have not remedied the situation much

Chris Poland - Return to Metalopolis
What a great instrumental album by CP! Killing is my business... had just gotten my attention, and yet again a mate gave me a tape telling me I should listen to it. All I remember of my first reaction is who the hell is this dude with these chops and phrasing, sounds so familiar but I can't put my finger on it.
Tony MacAlpine - Edge of Insanity
Found this the same way as the previous ones, got a tape from a mate etc. I really admired his melodic style and the fact that he plays the piano like a madman!
Come to think of it those are the only instrumental albums I still put in my player even though there have been many others I've liked and bought on vinyl and later on cd. I just keep coming back to those teenage feelings I guess
