I have a few but to narrow it down: Al Stewart- Past Present and Future. This is an earlier stage album when Jimmy Page was still doing guitar work and Alan Parsons was entering the frame and it's rich in historical reference and just incredible every listen.
The Church- Heyday. Just before their commercial success and it's an album that keeps rewarding you with sonic bliss over and over.
