Only the first 6 albums are epic with acoustic guitar sound. His guitar play is brilliant. Bruce moves to pop music since his 7th album with synths and full band sound but less impressing.

Bruce Cockburn (1970) - rating: ****
First introduction to his acoustic and emotional guitar style

High Winds, White Sky (1971) - rating: *****
Even better than the first album and more emotions are thrown in. I think this one is his best together with the follow-up: Sunwheel Dance. Read my review here.

Sunwheel Dance (1972) - rating: *****
Another highlight of his career

Night Vision (1973) - rating: ***
The album has 3 instrumentals and is about exploring different styles like blues and jazz but the emotions and great acoustic sound are almost gone at this moment

Salt, Sun And Time (1974) - rating: ****
A return to the more acoustical approach

Joy Will Find A Way (1975) - rating: *****
His last good album before getting more electronic
