Somewhere in Time is my second favorite. it came out in the wake of Bladerunner, Terminator, and Robocop, and I remember being deeply impressed with what Derek Riggs managed to do with Eddie to modernize him like that. I even had a wall poster of Eddie smashing through with a wry smile on his face.
Favorite would have to be "Axis: Bold as Love" by The Jimi Hendrix Experience.
