The first for me was John Wesley Harding, but I’m old ;-). Then I liked Nashville Skyline, found Self Portrait fascinating, funny, a real hoot (it was brutally panned by critics, who later realized they just didn’t get it at the time), loved New Morning and then Planet Waves.
Blood On The Tracks didn’t speak to me (Dylan himself has said he himself doesn’t understand why people would want to listen to his pain---the separation and divorce from Sarah is the source material of the album's songs), but by then I had gone back and absorbed Blonde On Blonde and the two before that incredible masterpiece.
