A toughie for me,
back in the 80s I would have said Escape-ROR
Now I give Infinity (an utter classic) through Departure the nod, specially if you cant a couple songs on DaD.
songs I have really came to appreciate over the years is Winds of march,

also from the era there was so much live stuff/videos.
If you were to include AtL and OtY
